    I've got some PIAA 510 lights in my aftermarket bumper that I would like to update to LEDs. Can anyone confirm an LED bulb that will fit? Maybe there is some more modifications that are needed to fit the cooling fins and extra electronics? I know that converting to HID in the 510s is not that simple due to bulb fitment.

    I would like to get more light out of the lights and switch to a yellow 2700k/3000k light for the bumper.

    Best, J4R

    LEDs in your halogen reflector are not going to give you more light. And they are definitely not going to get you more low color temperature light.
    Read this to see why that is a bad idea:
    https://www.tacomaworld.com/threads/why-leds-should-not-be-run-in-halogen-reflectors.454371/

    If you want LEDs and yellow light in a standalone 4" fog, I would suggest looking at:
    http://www.kchilites.com/industry/fog-lights/4-gravity-led-fog-light-pair-pack-system.html
    Though these are 580nm which is in-between yellow and amber.

    If you want more light projection out of your PIAA 510s, switch to a high efficiency non-coated bulb, like Osram Nightbreaker:

    If you want a flood light more output, but are less concerned about distance projection, consider a high wattage bulb:
    https://www.powerbulbs.com/us/product/osram-super-bright-premium-h3

    I don't know what the PIAAs wiring situation is, but you need adequate wiring and fuse to upgrade to high wattage 100w bulbs.

    I guess you really don't like LEDs. Can you answer my question?

    Nice research on LEDs in stock housing. Doesn't really apply to my situation since these are aftermarket fog lights and don't have a cutoff and the pattern is less important. I also don't understand your comment regarding the color temperature. Are you saying my housing will turn a yellow light white? The bulb determines the color, not the housing.

    Not going to spend $300 on new KC lights, especially when I already have a set of housings. Not sure where you get 580nm, but KC says the lights are 5000k which is not yellow or amber.


    100w bulb in a 55w housing? Sounds like a good way to melt the housing, regardless of the wiring.

    It isn't that I don't like them, it is that putting LEDs in a halogen housing is going to result in awful performance. LEDs require an LED housing.

    But yes, there are LEDs that do not require a cooling fan, like these:
    https://www.amazon.com/ICBEAMER-pai...e=UTF8&qid=1526662004&sr=8-10&keywords=h3+led
    or
    https://www.amazon.com/Orange-10-SM...&qid=1526664811&sr=1-30&keywords=h3+led+amber

    Performance will be significantly worse than stock.

    Beam pattern does apply as your PIAAs have a designed beam pattern. The 510s come in several patterns, including fog. So if you have the fog version, it has a cut off. If you have a driving beam pattern version, it wont. But it still will have a designed beam pattern based around the light source. Changing the light source to LED will completely mess up the beam, meaning they will not project nearly as far, and they won't light up the road nearly as much, while also inducing massive glare. So they will look brighter when you look at it, but will put out much less light.

    There is a drop down to select light color, you can choose 5000k or amber. Since amber LEDs produce no white light it isn't rated by color temperature, and instead is referred to by wavelenght if you want to know the color. The KC wavelenght is 580nm, which is right between yellow and amber.


    PIAA 510s are steel and glass.
