Toyota does not make it easy to enable the Daytime Running Lights on the Tundra. Nor do they seam to have any interest in helping anyone add them themselves. But that’s ok, like everything else it can be reverse engineered.
If you have an interest in enabling DRL on your Tundra you might want to click on the PDF file attached to this post and save it to your computer.
If you can follow some directions and are capable of soldering a few wires you can get the DRL working.
This design will enable your DRL to operate as follows:
q With Ignition Key “On” the Turn Signal Bulbs (27-watts) light up as the DRL.
q With Headlights “On”, the DRL will be turned “Off”.
q When using the Turn Signal, the DRL for the side you wish to signal will turn off function as the DRL and turn on function as the Turn Signal until the turn indicator is canceled. Once Canceled DRL function will return.
q If you would like to be able to turn the DRL system off at any time you can install an “Optional Switch” (of your choice).
This simple design has been installed for the last three (3) months on seven (7) 2007 Toyota Tundra’s. All have operated flawlessly.
If you would like to enable DRL using the 27-watt turn signals, as Toyota does, on your Tundra this low cost design will work for you.
I hope some will find this useful.
