How to Seal Headlights
Updated: October 11, 2024
If you have taken the headlights apart, make sure to seal them again afterwards. This will not allow moisture in, so you will prevent fogging and prolong the lifespan of your bulbs and wiring. Make sure to check that the lights are clean and there is no dust inside. You can use compressed air to remove debris from the headlight assembly prior to sealing.
- Apply a seamless bead of outdoor grade silicone to the sealant channel.
- Seal wires route opening with strip calk or sealing putty.
- Clamp the lens to the housing and let it stay in this position long enough for the seal to set. You can check the recommended drying time in the instruction of silicone that you used for sealing.
- To hold the headlight lens in place you may want to use clamps or ratchet strips. The choice depends on the headlight configuration.
- Once the headlight sealing is dry, inspect the seal. If you feel that the seal is not completely watertight, you may want to add some wicking silicone over the dried seal.

I bought a set of LED halo rings off e-bay, and I am happy with what they look. I believe, Toyota had to think of it prior to I did. lol
I must say, my truck looks completely different and way more aggressive with the halo rings in the lights. Mine is not too new, yet with the restyled lights it looks way better than in all-stock stuff.
I just bought a set of ‘Oracle Chrome OE Style Headlights w/ White LED Halos’ for my F-150, and have been searching around for info on how to seal them up against moisture or water leaks. I’ve read a lot about using silicone, but hear that silicone off gases and can leave a film on the inside of the lens. Is it really true that silicone can leave a film? And if so, what can I do to prevent that?
Also, should I get a set of gaskets fro the bulbs or are the aftermarket Oracle gaskets good enough usually?
Thanks so much.
Hi there, we normally use black silicone, and it does not leave a film. I’ve heard that the regular transparent silicone leaves a film though. This is the one we use, https://amzn.to/2nqNsHr (M1; No Outgassing).
Hope this helps!
Recently Purchased a set of Halo lights for my 1994 Mustang GT from Spec D on eBay. The cost of postage was the same as the price of the Lights. I complained but was told eBay set the freight price. Received quickly and looked good but very plastic construction. I had to cut away lots of the plastic housing which made it a one way installation. No return to original!!! this was not shown in the directions. the only support fixings were the adjusting screws and one clip, I think this is not good enough and I will need to put some extra support to stop vibration especially on bumpy roads. They look good and work OK!! , check out other suppliers with better fixings and stronger material. Maybe HID or LED globes in existing fittings might be improvement, but the look would not be as good. .
Hey Stanley,
Wow, that sounds like the manufacturer has sent you a set of lights that came with a defect, as you are not supposed to cut out the plastic from the lights. This sounds like something went wrong during the manufacturing process. I know, that sometimes lights from Spyder, Spec-D, and CG can be defective, so when our shop gets a shipment, we test the lights right away. This does not happen too often, yet there is a chance to get a defective piece. I am sorry to hear, that you got such an assembly and had to go through the inconvenience.
