For the reverse light I ordered the BA15 5-Watt LED bulb in white. they did not fit as the light housing (bulb) touches the lamp (truck) housing by probably 1mm and keeps the pins from engaging. So I unglued (yeah they are just glued together) the bulb housing from the light housing JB weld it it and put it back together but gave it about 2mm of space and put it in the reverse light.. I hot wire it and its SUPER BRIGHT !!! but have not finish installation yet.... oh yeah I sheared the wires on the second bulb



live and learn.
The mod is easy as long as you dont twist. all you have to do is pull apart straight and is best if you use a screwdriver (a tiny screwdriver) and glue it back with the necessary space for the pins to catch the lamp housing on the rig.
