I had a pretty nasty leak into my stock ones and I broke the mounting clip thing that holds the bulb in place so I ordered black eBay Diamond lights (just OEM look but black housing). Would it be a good idea to go around the whole headlight seam with extra sealant before installing or are they generally OK quality wise?

 

Yeah, I would...

I had that issue with my old Ebay lights, they leaked like crazy.

 

If you decide to reseal them, as much as I hate to admit it, Nissan headlight sealant is MUCH better than Honda headlight sealant.

 

i would have to admit nissan sealant is better even tho i work at hnda

 

Don't open them up, but yes run a bead of sealant. I used clear RTV silicone on my black housings. You can see it a lil bit in the pic, You can't see it when installed. Either they never leaked, or with my clear silicone I don't have any leaks or even condnesation.

 

Since ebay headlights usually have crap sealant, I would suggest resealing them for the best results. Get some butyl tape (aka window weld) and reseal them. Heat the headlights in the oven at around 250 degrees for 7-10 minutes. Run the butyl tape around the headlight where the original sealant is, reheat same temp and time and make sure to go around the headlight and tighten it up with clamps after so the glue makes a watertight seal. I just retrofitted a set of ek9 headlights and have done others, butyl tape every time.

 

Yes, DON'T open them! They like to warp, ask me how I know.

 

I don't know about all that. I opened my CTR knockoffs for my projector retrofit, and they didn't warp at all.

 

Thanks for everyone's replies, I wasn't going to bake them, but just do an outer coat like you guys said

 

Well I do. They warped..
