Led tail light, warning light dash help

Post by c_doughty1 » Sun Feb 23, 2014 3:52 pm

Ok I've installed led tail lights and although they look good, they throw the brake light warning light as soon as I turn on the cars lights. I have two options I think:

Option one I think earths the error thrown in the sensor which is a white wire with a green stripe through it. If I earth this then in theory this will cancel the brake light warning light, although I've never earthed anything so I'm not really sure how to do it.

Option 2 is fit resistors to the rear light wire and brake wires abd the earth but I don't know which ones which and if I need to put a resistor on each of the brake wire and rear light wire and the black earth or just one of them as I'm not sure which would throw the error light on the dash.

This is the picture of the wiring, the top is the brake light with the black earth and red/black which I'm not sure what that is brake or light and same with the orange one.

You bought the wrong type of LEDs. You need Canbus LEDs with built in resistors. :ugeek:

Using LEDs make sens only if this will save some electricity in your car system. And basicaly this is what they do. If you will use resistors then whole this theory disapearing as they will use as much as you save on powering LEDs. So only option is number 1 or go back to standard bulbs. And don't buy any canbus bulbs because preludes never seen canbus system

Like Pushky wrote they have resistors built in so you wont save any electricity. And you have to pay for them while earthing one wire cost you nothing

Canbus work fine!
Who cares about saving electricity. It's all about having brighter, whiter lights. :P

I don't know anything about wiring up resistors though. Sorry.
