There are kits out there to add an extra bulb to the section of the taillight lens bezels next to the ones that light up in the stock configuration, giving more light. If I find the kit, I'll post it - I think it's basically just a harness that someone makes. Don't know what other implications that'd have for your electrical system though (drawing a lot of extra power than the system was intended for). . .
