Before yesterday, none of the front signal lights worked, but my father changed the bulbs and the front driver side works. The only one not working is the front passenger side, we noticed that their are a strip of wires under need the signal bulb on the driver side, but their werent any underneath the passenger side, does anyone know what that means? Does it need those group of wires? and if so what is it called? Thanks
yes, l checked the bulb socket, it is slightly rusted, l scratched at it and took some of the rust off...still no luck

Forget the wiring, if a new bulb did not fix the problem, possibly the bulb socket is corroded or rusty, check that.
