Passenger side burns out in about three days, I've tried both the 4157 and the 4114 in clear. Any idea's? I've heard that running a single element bulb last longer, also heard the amber 4157's last longer (can't imagine why?).
Examine the socket. It will be melted and the pins will be corroded. Get a new socket from the stealer and crimp it in, problem solved. Because a 3157 or 4157, by design, was never intended to remain lit on the bright filament, the economy plugs will melt over time.
I've been running amber 4157 for years now with 2 different trucks. The 4157's seem to be lasting much longer. My GMC however, did get the plastic hot enough to start to whiten the lense. I tried to run LED's with my 07 and they were bright but the beam was not using the mirror at all so all you had was a tiny, dime sized beam of light that kinds defeated the purpose of having lights on in the first place. I have pics of the LED's in my garage.
