Rear Brake and Signal Lights.

I replaced the Drivers Side Rear Bulbs, 1326, with Sylvania Brite White Leds. Now when I activate the Drivers Side Blinker, the dash indicator flashes twice as fast. ???l
What are the best and brightest upgrade LED'S for headlight Bulbs, Fog Lights Bulbs, and all Rear Bulbs? Thanks, Steve

 

led bulbs draw very little current so your flasher sees led as a burned out bulb. you will need to change flasher or they sell resistors you can wire in

 

Steve, anytime you change up into LED flashers on our Tundras you will need to replace the Flasher relay located just underneath the panel cover directly in front of the driver. 4 bolts hold the panel on, and it's as simple as using a flathead screw driver to slide the old relay up and off its mount point that is held in place with a slim plastic adapter. Swap the mount adapter onto the new relay, replug the adapter, and slide it back down into place on the mounting point with the adapter that's attached to the new relay. I would suggest buying the relay from Diode Dynamics. I bought the CF18 Smart Tap, along with 2 sets of amber Front turn signal LEDs. Hope this helps you some brother.

One Edit Note: The flasher relay is only needed to fix the hyper flashing issue with the signal lights, and does not affect you brakes or back up light applications. Depending on if the LED bulbs you are using are compatible with your bulb socket type(CK or Non CK) for signals than you may have issues. I attempted using the Sylvania Super bright 3157A's and was shocked to find out they did not appear bright or as intense as I had seen non other applications. The Diode Dynamics bulbs worked straight away.
