Spec-D headlights: design and configuration

Spec-D offers several headlight design options to meet the needs and expectations of American drivers. They are available with tinted or clear lenses and with chrome or black housing. The combination of these elements allows Spec-D to create a fully custom or OE-style headlight assembly for the major vehicle applications. Except for the plastic parts, Spec-D headlights are available with different accessory lighting solutions. Here are some of the accessory lighting this manufacturer uses in their headlights development:

  • LED accents;
  • LED strips;
  • LED halo rings;
  • CCFL halo rings;
  • U-bars.

Spec-D Projector Headlights

Many of the Spec-D headlights feature a built-in projector lens for the low beam. Such headlights are called projector headlights. If they come equipped with the halo rings, they are listed as halo projector headlights. Spec-D headlights focus on the light coming from the bulb, which acts as a light source. If that is the headlight type you are interested in, make sure you use the right bulb type to ensure proper visibility on-road and safe drive.

If your vehicle features factory HID bulbs, make sure the aftermarket Spec-D headlight description says the lights are designed for the HIDs. Otherwise, you risk getting that dangerous glare and poor visibility at night. Spec-D headlights that are not noted as the ones to work with HID (xenon) bulbs are designed to work with the halogen bulbs of the pre-specified bulb size, which usually does not correspond with the OE bulb size.

Spec-D Halo Headlights

Installation of halo headlights is a cost-effective way to customize the front fascia of any vehicle, so no wonder, that Spec-D halo headlights are that popular among American car owners. Spec-D employs 2 main angel eyes technologies in their products: CCFL and LED halos. Some headlights feature 2 built-in halo rings, some feature only one halo per headlight assembly. Both technologies ensure lasting service and custom look, yet CCFL angel eyes give a more moderate glow, while LEDs are way brighter. Halo headlights by Spec-D are available in 3 major design options:

  1. Black Spec-D halo projector headlights feature black housing and clear lens;
  2. Chrome Spec-D halo headlights feature chrome-plated plastic housing and clear lens;
  3. Smoke Spec-D halo headlights have got chrome background and tinted lens.


Spec-D Fog Lights: Overview

Spec-D is one of the leading manufacturers of aftermarket lighting in the U.S., so they offer not only headlights but also custom fog lights for the most popular makes and models. In their selection, Spec-D has a variety of styles and designs of fog lights. The simplest fog lights feature the same design as stock fog lights. When marked as ‘euro’ in the product description, fog lights do not have the bulbs in the kit and are supposed to be used with the OE bulbs. Projector fog lights feature a built-in projector lens in each fog light. It ensures precise focusing. Though, it is a must to adjust the fog lights properly to benefit from them in rainy or foggy weather.

How to adjust Spec-D halo headlights?

Spec-D strongly recommends adjusting headlights once they are installed on the vehicle. It’s fair to say, that all aftermarket headlights are adjusted the same way. Each light assembly has got adjustment screws at the back. The light direction is adjusted by rotating these screws.

Would be nice if the instructions gave you the adjustment screw layout. Trial and error sucks. Diagrams make it easy.

I've bought the "tuning" series for my focus, LED DRL Switch Back Smoked w/ Black housing. They look awesome compared to the OEM ones, but......
To say they're true DRL/ Switch Back is a misnomer. A OEM switch Bck will kill the white running light while the amber turn sig blinks then back on for the white LEDs after the turn/flasher, mine blink amber then to white (back and forth) while activated also comes with an additional amber turn light that Flashes while activated probably due to the brightness compared to other stock DRL/Switch Bck on today's cars witch are very BRIGHT! The fitment is great the look again is GREAT! The DRL function doesn't come on with the ignition being on (like today's car lights) have to turn on my parking lights. fixed that issue by finding a key-on terminal in the fuse box and the proper parking light lead to the pk light on the pin connector. Cut soldered the wires @ the pin connector, now front DRLs work w/o the rear lights being on during run time.

My only 2 questions are:
I have found LED fan-less fog/headlight for the H1 style bulb that mine are. I know they'll fit, but do you suggest I install them?
also what is/are the two pigtails coming out of the back of the headlight units? They both have a weather proof 2 wire pin connector.

Spec-D headlights are pretty much okay, yet I didn't like that they do not include bulbs along with the headlights. That's why I'm giving them 4 stars. Cheers!

After headlights of my BMW faded and cracked, I had to think of the new headlight set. BMW dealership wanted something around $1.5K for ONE headlight, so I decided that I do not feel I want to spend that much and ordered Spec-Ds (they were around $350). They look cool and they've been on my BMW for around a year, and everything's fine.

I like my Spec-D lights for the F-150. They look great and are cheaper than the OE headlights.

    I am considering purchasing spec D lights for a 2008 Impala but notice that there is only one light source I also want the HID kit and don’t want to lose my high beams will the H4 work with spec d headlights

    1. Steven Davis says :Reply

      The bulb size depends on the particular headlight model you are looking at. In general, Spec-D does not recommend installing HID kits into their headlights, as HID bulbs are longer, than the regular halogen bulbs, even if you pick the right bulb size. So most likely they will not focus right. However, this rule works for all aftermarket headlights that come with the pre-installed halogen bulbs (IPCW, Spyder, Recon, etc). As for the high and low beam functions, you can keep both if you pick a dual beam HID bulb.

    How to adjust high beam on spec d projector light on 4 gen eclipse

    1. Susan Andrews says :Reply

      Hey Joseph,
      Please refer to the instruction above. It is generic and works for any Spec-D headlights, regardless of the vehicle.

  3. Elvin Unger says :Reply

    How can one tell if the lens on halo headlights are plastic or polycarbonate or plasti?

    1. Susan Andrews says :Reply

      Hey Elvin,
      All new Spec-D halo headlights have polycarbonate lenses. Some older models used to come with plastic lenses, though.

  4. Ed J says :Reply

    Mr. Davis if you are still monitoring this site, I have a 2007 Ford Edge that naturally has two head light bulb per assy….. low/high beams are separate. My question is with the Spec-D light that is 2LHP-EDG07 JM-TM which is suppose to be a replacement what is the bulb for the projector that I assume runs as both high & low beam? Is it a seal unit? I can’t find out were those spec’s are.
    thank you in advance Steven, Ed J

    1. Susan Andrews says :Reply

      Hey Steven,
      Aftermarket headlights normally require new bulbs, as the bulb size differs from what you have in your stock headlights. These Spec-D headlights take H11 bulbs, which are dual-beam (high/low). It is not a sealed beam, you just need a bulb like this one (Philips H11, on Amazon https://amzn.to/2nq0AfW). You can select any brand, Sylvania, Osram, Philips… Just try to avoid those no-name brands, you know, not all of them are good.
      Hope this helps!

    I have the Spec-D Tuning 2LHP-SIV99GL-RS Headlights (Projector Smoke LED Lamp) and my bulbs burned out could u tell me what size the bulbs are in my high and low beams and one of my halos bulbs burned out could you Also tell me the bulb size for that

    1. Expert says :Reply

      Hey, can you tell me the year, make and model of your vehicle? Seems like Spec-D conducted a series of changes in their part numbers. I want to be sure you will get the accurate info.

  6. Ed says :Reply

    Hello Steve or Susan, I would like to ask if you know what the wattage is for the row of 10 LED’s that run along the top of the spec=d lamps I have for my 2007 ford edge. Where the wire goes thru to the row I see a stamped 12V/2W…I’m assuming that is for each LED but if not please advise.
    Warm regards and thanks, be & stay safe, Ed

    1. Expert says :Reply

      Hey Ed,
      That’s right, the wattage is noted for each LED, while 12V is the normal operating power for the vehicle headlights.

  7. Psychlone says :Reply

    Can someone PLEASE help me to upgrade my low beams to HID and high beams to LED?
    So far I’ve purchased 2 separate sets of H1 HID bulbs and so far none of them physically fit in my Spec-D 2LHP-TIT04JM-TM.
    The H1 HID bulbs I just received have the flat part of the insert on the wrong side so it will not sit flush into the receptacle.

    Some advice on a set of 5000K HID for the projectors and 5000K LED for the high beams would be awesome if anyone knows what actually fits my 2LHP-TIT04JM-TM.
    Thank you!

    1. Susan Andrews says :Reply

      Hey there,
      These Spyder headlights are not designed for HID/LED upgrades. So you can try different bulb designs, if you decide to go that route. Alternatively, you can just pick a good set of headlight bulbs by Sylvania or Philips and enjoy bright and clear light.

    I purchased new projector headlights for my 2009 gmc denali yukon. The low beam needs to be adjusted up. I see the high beam adjustment screw but not the low beam?

    1. Susan Andrews says :Reply

      Hey Chris,

      Can you provide the part number of the headlights you have purchased for your Yukon Denali so that I could look it up for you?

      Thank you.

    For Spec-D Projector Headlights Dodge Ram (94-01) LED DRL Strip – Chrome, a friend’s installer claims that this model does not include beam adjustments, which is hard for me to believe. The beams currently point too low. Might you be able to send me a pic that indicates the locations of the adjustment screws?


    1. Susan Andrews says :Reply

      Hi Mike,

      I do not have a picture of the particular headlights you’re asking about, yet I am pretty sure, that all Spec-D projector headlights adjust just the same way.
      Check out this article that has pictures of the adjustment screws (you may need a screwdriver to adjust your lights):
      How to Adjust Projector Headlights
      By the way, there are good pictures of how can adjustment crews look on different aftermarket lights.

      Thank you!

    I have spec-d for my 2005 f150. Low beam h1 just went out on passenger side, how do I change it? Didn’t want to end up breaking it when I pulled the assembly apart to get to it. Once I take the connector pins off, do I just take pliers and bull it out?

    1. Susan Andrews says :Reply

      Hey Lauren, yes, just gently pull it to remove.

  14. Michael A Hoff says :Reply

    We have a 2011 ford fusion with a Spec-D led headlight assembly installed. How do we remove the plastic cap that covers the low beam lightbulb? Thanks! Mike H.

    1. Steven Davis says :Reply

      Hey Michael, I believe you are talking about the headlight bulb cover. If that’s it, just press the tab to release it. And pull on. Make sure not tp break it, as it’s plastic and may appear somewhat fragile.
