I just don't like them.

I fitted LEDs to my Challenger and no way do they glow as evenly or as soft as the original lamps. To avoid hot spots (and to get them bright enough) you need an even spread of the LEDs over the whole surface. Then they still don't look right to me.

I am going to put standard stop/tail lamps back in. One thing I might change though is to paint the reflectors gloss white instead of silver. I have heard this gives a nicer and more even glow to the lights.
