Some more questions ....
1) Do you have a picture of the underside of the finished product showing the puddle light installed? How did you finish it off?
2) What did you use for google to find it (puddle light led strips)?
3) The yellow blinker light, you tinted yours, I am not planning on repainting the mirrors. When you were grinding the slot, did the paint want to heat and burn? Do you think if you go slow and check the fit often, it will look ok? Since I am not painting black, I don't think I will tint it, do you think leaving it clear will look ok? I have not looked at any "how to" on tinting yet, can you do different colors?
I bet there will be others before this is over. :-)
