I've got two of the KC HiLite long range slimlites on my truck. They are pretty bright, but I want something brighter. Does anyone know if I can just swap the bulbs and buy brighter bulbs or do I have to get rid of both the lights and buy a new model.

 

bulbs can be swapped. what wattage do you have now? i know i had 130w and 150w bulbs that came with my first set and my current have 55w for driving but you can also do an hid swap

 

I swapped HID's into mine. Well worth it. You just have to drill out the hole where the stock wires run through to make it a little bigger, but other than that it is easy.
