I have seen some pictures of the 3G TL-S that have a red illuminated light on their door. Like Steven Bell, he has the red illuminated door sills, and also the light on his door is red too. I own a TL-S as well but the light is just regular white. What kind of mod was it? Did you just replace the bulb with a red led light?

 

I also have the RED lights in the doors. I replaced the white bulbs with red LED's. I have the 5 LED that has one LED facing forward and the others facing each of the four sides to better distribute the light. You can get brighter if you want brighter. Wedge size is168/194. Very easy mod. Just pop off the light cover, pull out the old bulb and push in the LED, DONE!

 

Any idea where i can buy this red led bulb you are talking about?
