After I washed my car this past Thursday I went to the drag strip. I realized on the way I blew another bulb and I had no left blinker. The water was starting to seep through the cracks in my lenses again. I had taken them out once before and put about 10 coats of clear coat over them sealing up the cracks and it held for about 3 years, but now enough was enough. No way in hell was I paying 70 bucks a pop per turn signal houseing so I made my own lenses outta 1/4 thick Lexan glass. Lets see a road hazard crack these babies!!

Materials:

1 Can of DuPont Chrome Paint
1 Small piece of Lexan Glass
1 tube of clear silicone
screwdriver
10mm and 11mm socket and ratchet

Step 1:
Remove the turn signal houseings from the bumper.


Step 2:
Remove the lenses from the houseings


Step3:
I cleaned the inside of the houseings with some Krud Kutter then re-chromed the insides with DuPont Chrome paint. I traced the old lenses over on the Lexan to match up to a perfect fit.


Step 4:
After your paint is dry, run a thick bead of clear silicone around the edge of the houseing. Make sure to center up the lenses and run your finger around the outside edge of the houseing and lens, add more silicone if needed to fill in the gap. I also siliconed any cracks I could find on the back side of the houseings from old age.


Step 5:
Let the sit over night or at least a couple hours to let the silicone cure up and reinstall!

Looks like ya did a pretty good job there. That should be very durable as long as the lens does not get knocked loose from the housing.

They do look good but I'm wondering too on how long it might be before the lenses would loose adhesion from the housing with just using the silicon to hold them on.

I've never used, but I've heard that RTV sealant that is pictured is pretty tough and holds.

Nice detail, no doubt!

Just wanted to know, cause I just tried this, HOW did you get the lenses off of the housings? It took forever to get them off!!
mark_arch
Oh yeah, also, what did you use to cut the Lexan material?
Doug
I have used that exact permatex RTV silicone and it holds very well. They should last a good bit and what the hell you just make another one if it falls off in a year or so.

Nice job.
