Some nice light setups here...to me, the ones either integrated into the bumper or really tucked under (the way smoothee has his) make much more sense for a truck since there's little chance they'll get knocked off by something.
I've been debating the light bar/cube setup for awhile now, but I think I'll start with
these backup bulbs from Diode Dynamics. I figure 510 lumens each ought be enough...if not, maybe I shouldn't be backing up!
BTW, if y'all haven't heard of
DD, give 'em try; those folks make quality kit right here in the USA and they've got the science behind their bulbs and lights, too. Not many (if any) import brands can say that...and no, I've no affiliation with the company.
