Travis: The before pics were just as the sun was going down with heavy cloud cover, so very minimal ambient light, but there was a touch. I should have actually taken the pic of the map lights with one of each bulb type in, as I compared the two at that time. The regular bulb with the greater amount of diffused light seemed to cast less defined shadows and therefore the coverage appeared to be more greater. What I did notice though is the LED's seemed to get brighter the more they were used...almost like a break-in period...or maybe I'm just imagining it.
SVT4MT: Thanks to the youtube video for the map lights, they were easy to take apart. The 194 style bulb is a HUGE PITA to get out of the socket and I did need the needlenose pliers. Finding a good place to mount the LED boards inside the housing was a bit of a pain as there is not a lot of flat surface area, but I did manage. I wanted to make sure they were aimed correctly to throw off the maximum amount of light. As for the rear, my SCREW rear light is only a single festoon bulb. The light housing is two parts. The part that holds the bulb and the switch, and then the lense attaches to that. It's best to take it all out in one piece, then remove the lense. Mounting the LED board for the back was a little easier as there was a nice flat spot to stick it too.
Whole thing took less than an hour including taking the pics.
