    Hey guys... been sitting on some LED bulbs I bought on E-bay in the fall, because they won't light up in my stock wiring harness.....

    Figured out, the bulbs are fine.... but for some reason... they just don't work in my truck. A friend of mine, thinks they are not putting out enough resistance, and the computer doesn't realize they are there... suggests I wire in a resistor to fix the issue..

    Anybody have a similar issue??? What did you do to fix it??

    LEDs are polarity sensitive. When you install them have you made 100% sure that you have the polarity correct?

    Absolutely... actually, I've done tons of work with LED'S before.... I've exhausted every fitment issue, as well as install. Looks like a resistor will be needed.

    Has nobody tried buying a LED conversion bulb yet???? I know that with a 3rd Gen 4Runner... you'll get Hyper flash issues.... same with a Cavalier... but in my 2nd Gen Taco.... it just doesn't light up at all..... ?????

    The Tacoma has no "computer" attached to the lighting system.

    If the LEDs aren't coming on, they're either incorrectly installed or they are bad out of the box.

    The front turn signal sockets are wired such that they require the "CK" type LED or they will blow the turn signal fuse.

    A resistor, or electronic flasher (available if you don't have DRL) will be needed for LED turn signals.

    And FWIW, LEDs have HIGHER resistance than lamps.
    Anyone who doesn't think they have enough resistance is not someone to seek electronic advice from.

    Alright folks.... the bulbs were installed in a 01 Cavalier, and they work... only they Hyperflash..... so there is obviously something to this....

    The bulbs work, it's something on the Tacoma's end..... P.S: The guy I'm getting to help me with diagnosing this, has helped me with many Electrical projects on this and my other truck. He knows quite a bit about this stuff...... but we're having issues figuring this one out.

    I've contacted the seller, exchanged many e-mails, and he doesn't know why they are not working either....


    These are the bulbs I purchased.....

    Anyone buy these before??

    Now that I see the bulbs you have purchased, I can give some recommendation on ideas. These bulbs have an interesting thing, that also goes with the regular bulbs that fit the same socket. I usually have to take the tiny metal contact that loops under the bulb and slightly bend it out, then take the socket itself and bend the tabs slightly so that they have a bit more "arc" to them. Then reinstall. Another thing you can do is used a multimeter and measure the resistance at the back of the socket to verify proper connection inside the socket. The 3156/3157 bulb sockets are NOTORIOUS for making poor connections. Over the past say 5 years I have had to make numerous socket repairs on these. One bulb will plug in just fine and work, the other wont.

    Another thing to look at is the application. A 3156 bulb/socket is designed for a single "filament" bulb. The 3157 is for a dual "filament" bulb. If you put a 3156 bulb into a 3157 socket, it may very well not work. Same goes the other way.

    Thanks for the ideas man... I'll give those a shot! :)
