Has anyone onstalled led switchbacks on a 2011 Taco pre-runner off-road with DRLs? I am researching this and have come up with a potential problem.
One thing is that the stock DRL/turn signal bulb is a 4157 dual element with 2 wires on its socket. When you install LEDs to replace incandesents you will get hyperflashing (rapid flashing) due to the lack of load with the LEDs. To correct this you have 2 options: 1.) install 6 ohm load resistors on the wires to the light. Here is one of the problems: the 4157 socket is 2 wires not 3 like most 4157 or 3157 have. Normally you would attach the load resistor between the turn signal wire and the ground wire on the socket. Since there are only 2 wires on the socket (one for the DRL and the other for the turn signal) how is the resistor grounded? Do you attach one end of the resistor to the turn signal wire and the other to the body ground or do you attach the resistor across the 2 wires? The 2nd option; 2.) Change the flasher relay to an LED type. I have tried to find an LED flasher for the Taco with DRLs and have come up empty. Has anyone come up with an LED type flasher for this application?
Help with this would be greatly appreciated.
Thanks
