Well today I replaced all of the regular bulbs that came with my rig and went with the superbrightLED replacements. For the marker lights (194 bulbs) I went with these.
In total I replaced 7 amber bulbs (The factory ones were clear and relied upon the lens) and then 6 red ones.
The tail light replacements were these as a direct replacement for the 3157 bulbs. They also offer these in both white and red. I went with red just because I can.
These pics make it hard to see the difference during daylight,..but at night,..WOW what a difference!!
