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.

Really impressed with the brightness. I will definitely recommend these to everyone I know!

No way you won’t be seen

These switchbacks are bright as sh*t! I felt like a semi rolling down the highway and switching lanes at night! These particular examples proved to not be error-free on their own in my ‘18 Silverado, however all I had to do was let Diesel LEDs know the issue and they sent me all the resistors I needed free of cost! Swift, friendly customer service and they stand behind their products! Note about the resistors: mount them on metal and away from wires and plastic! These babies get HOT HOT HOT if left on for a long time, such as activating your 4-ways. Still though, the illumination is second to none!!!

Very bright!

Great replacement LED lights and super bright. Love that they don't need separate load resistors. Install can be a little tricky (at least for my '19 4Runner) due to the extra length compared to the OEM bulbs.


Bright as hell

Turn signals

Amazing super bright i highly recommend it
