Solves the issue LED Blinkers have had since day one.

LEDs have always had one big issue when it came to using them in a blinker application, they Hyper-Flash. This is because LEDs do not create enough resistance to show the vehicle that there is a working bulb there. So the vehicle causes the blinker to flash rapidly which can be extremely annoying.


The Lumenex Switchback Bulbs solve this issue with their built in resistor. This means this bulb is 100% Plug and Play. We've designed it this way because we know that no one wants to splice into wires and install a cheap resistor on their new or used vehicle.


Switchback Function

These Switchback Bulbs are meant to be used in an application where the front running light, and the blinker is the same bulb (they function like this on most all trucks) Switchback Bulbs functions as follows. When the running light is on the bulb is illuminated white. When you engage the blinker, the bulb begins to flash yellow. When you disengage the blinker it returns to its pure white color. This makes the front end of you vehicle look a lot cleaner, with a modern all white (when coupled with LED headlights) look without any amber colored lights. 


These will still work on vehicles that use the front bulb only as the blinker ONLY 

If your front blinker functions ONLY as a blinker and not as the running light and the blinker. This Switchback Kit will still work for you. HOWEVER only the yellow blinker function will work on this style application. But it will still work on that application. This is because the vehicle is not set up to give power to the tabs that illuminate the white running light part.

2017 Tundra Amber Blinker

Love the light. My only concern is my first set lasted less than 2 years before one of them quit working. They did not have the cooling fan built in like the new style. Hopefully these will last longer.

I buy all my LEDs from these guys. Fast shipping excellent service. Their LEDs are super bright especially the backup lights. You'll make a mistake if you don't buy from here

Could not install

They did not fit my truck. The site had them labeled to fit my 2011 f150, but they were too big. Had to order different ones. Reverse lights are amazing tho

They just work right!

These LED bulbs just work right, dim for parking lights and really bright for turn signal. No hyperflash issues and they fit right. I first tried Dieselleds a few years ago for their LED back up lights and have since bought all my bulbs here. They are more expensive than some stuff you might find on Amazon but these are built right and last. I tried some Amazon LED bulbs after purchasing my first set of reverse lights and the Amazon bulbs are long dead while the reverse lights outlived the truck and are now in their second vehicle. Yes, I love these bulbs!
