Just put on my new fenders and i made a boo boo. For the side marker, I file down the hole a little too big. So now the light won't snug in. Is there a way to fill in the gap? It's about 2-3 mm too big. Now it's hanging kinda loose. Oh and it's carbon fiber

 

sounds like ur screwed. get something to install arond the marker that will take up the loose space. like some stip calk maybe.

 

You might be able to fill the hole carefully with a fiberglass repair kit.

try the repair kit mentioned above.... Just fill double what you need and SLOWLY FILE it away....


Measure 10 times, cut once....

 

I got it working now. I used the black silicon. Pasted some of it onto the back of the light itself, now it's staying in there.
