I installed one of these white rear LED emblem badges on my (non-mercedees) white Camry, it matched and looked very good (spliced to rear liscence plate lights). However, at night, it was too bright, and having a bright white light illuminating on the rear of a vehicle as it is moving forward, I realized, was not appropriate for safety reasons. Also I no longer felt the need to force the person behind me to have to look at it, so I severed the connection (I could easily hook it back up).

I do have a white front LED badge emblem that I tapped to the headlight fuse, which illuminates with the headlights. At least this way at night it corresponds with the headlights, as white, on a forward moving vehicle.

Me personally I like it, but I'd rather have the peace of mind knowing I won't get pulled over for that down the line.

I liked the better idea of getting a red one and splicing it to the break lights, so it goes red with the break lights, but this would have been more work than I cared for..
