I've been trying to figure this out for years... Versions 1.0 and 1.1 that Nakman and I came up with were not nearly bright enough. Made OK camp lights. The solution on MUD looks good but I don't want to cut my bumper. And for the OP its DRL's not fogs.
I've been chatting with Nick from Expedition Lighting Systems about the same solution. He has a LED light that will fit but would need a housing or bezel made to look clean. This would be another DRL solution which is what I want personally.
Rigid Industries has some flush mount lights now that could work. http://www.rigidindustries.com/d-ser...ghts-s/191.htm
Christo may have some personal experience with them?
