I have watched a few videos on youtube where guys have swapped their interior lights to LED's and it makes the car look a lot better. Does anyone have links to ebay/ amazon for a product they used and loved?

 

From all the ones I've used in the past.

I started using these for my GS. Interior/exterior. The flat panel style is what I see more of now. Though sometimes you need to do some trimming to prevent shorting issues. Example on the door courtesy lights bulb holder. Since the bulb holder is metal rails. I haven't encountered any other locations.

Are you talking about the LED's like the overhead panel light and such? Or LED's like on the radio/nav unit and gauge cluster?
