I'm starting to look at adding additional lights to my truck.. I have a TJM T15 brush guard and a Safety Devices roof rack.. so I have the possibility of adding up to 6 lights.. I'm not sure which ones I should use.. I was thinking Hella 550 Fog Lights on the brush guard since I don't have fog lights.. but then i'm not sure what I should do on the top.. should i go for all 4? Are the Hella 550 driving lights useful at all? They'd be used for both on-road and off-road driving.. off-road doesn't need much distance since the trails I go on are generally pretty dense with trees.
