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.

Awesome switchbacks

Awesome lights very bright when flashing and when not they blend so well with the led headlights and fog lights I picked up from diesel led. Order all my lights in a package deal and have been and will continue to recommend diesel led to everyone.

Received, installed, one week into use they seem much brighter, match in color, and the quality looks to be there. Feels much safer driving at night thanks to DIESELLEDS

The turn signals are crazy bright! 10/10! I’m just not sure if I like the white light instead of the amber running lights. Nothing shows up like amber day or night. Wish they had option of either color as running lights. Very nice quality.

Lumenex switchbacks

They’re perfect. Fit perfectly, no hyper flash and bright as heck. I wish The led running light was a little bright but amber flash is beyond bright. Great product

Does it’s job
