I have a relatively easy opportunity to add a pair of stop/turn/tail lights to the back my camper shell by using a standard 1157 dual filament bulb in 4" round fixtures that are already installed as extra reverse lights. As I have recently mounted a pair of Hella FF75 fogs in my rear bumper, I do not need the reverse lights anymore, so... .
My question is this--
is the stock tailight wiring sufficient to let me simply solder and shrinkwrap a pigtail to the individual stop/turn/tail wiring at the oem tailight harness and then use the oem circuit to simply light up the additional 27/3 watt bulb on each side, or do I need to use a relay from the pigtail to activate the additonal lights?
I already have extra power available at the rear of the truck to use a relay, but it seems to me that if it is safe to use the existing circuit for the extra 27watts (that's only 2 amps per side ONLY while there is a turn signal or brake light on, the tailight uses the smaller filament at 4 watts, which is practically nothing, right?) then it would be MUCH easier to not have to wire in extra relays for only a 3 amps per side!!
ALL opinions welcome, of course. TIA
