good looking out, i might have to order a set of these. no more resistors either lol
That may be premature based (in theory) on what I've read here. If you buy the 4114-compatible LED's, the voltage, based upon the description of the charging circuit, will still exceed the voltage of the LED by more than a volt for some period of time... When the battery is fully 'charged', the voltage could be 13.2 - 13.8 volts, depending on the year of your vehicle, the condition of the battery, the condition of the alternator/generator, and the condition of the electrical grounds.
No matter how you slice it, voltage will be variable; I don't know how well the LED's hold up +/- a volt or more from their rated voltage. Based on other experiences documented here-in, it's lasted at least 6 weeks... When I replace my 4114's (incandescent) again (soon - one is out as I write this), I usually get a year out of them before they go... I'll be checking out the ground on the nose of the truck next time I replace them... as well as replacing the lens assembly, because the reflective material has flaked off on the passenger side (entirely) and 30% or so remains on the driver side. Since DRL's don't help the driver that much in the daylight, I don't see that the price of the LED to get 'white' (or amber) light is worth it; although they may look 'hot' on the truck.
But then again, that's why I'm replacing the lenses; it looks like my black Denali has 2 black eyes; the reflector loss really affects how it looks...
I think I'd rather find a 12.8 volt output regulator (go back to 3157's), which should be 13.1 to 13.5 volt input to make it work... Anything over that will be converted to heat by the regulator; that seems to be the most correct way to 'fix' this issue, in my opinion.
