does anyone know why when you switch your DRL from halogen to led the led won't light? i tried a decoder with no luck and then i tried with just 1 halogen and that worked with just the led on. very frustrated at this time. this is on a 2007 TL, any help is a blessing. thanks

 

LED needs 12v to fully illuminate.

DRL socket only provides 6 volts to the bulb. That's why the halogen bulb lights up very dim. It only gets 6v.

When you apply 6v to a led bulb it won't even light up. In the rare chance that it does light up, you will notice only half the LEDs will light up and the ones that light up will appear very dim. Most of the time they won't even light up at all, just like what you are experiencing.

You need a relay harness that will give power to the DRL bulbs directly from the battery which is usually 12v-14v

 

^all of that and a bag of chips

 

i have seen different type of resistors and harness for this but not sure for the correct one? any ideas? this is my first TL and love it and want it to last for years to come!

 

by the iJDM toy harness......I have it and have had zero issues

 

hanks, i will try it and put and end to the issue!

 

This is my first TL and playing with electronics. What do you mean a relay harness? What does it do and will it provide the said 12v to make the LED light up =D?

 

this a relay harness that hooks up to the battery to get 12v. to the led lights so your original harness only has 6v.
