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.
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.

I bought the reverse lights and turn signal for taillights and the switch back turn signals for the front, I could not be happier! No hyper flash and super bright!
Work & look great!
I have lots of quality lightbulbs from this company
Leaving on a long 2 week driving trip and I wanted more visibility for my Ram while on the road. Installed the lights on the rear and I am shocked at how visible these really are. If someone were to run into the rear of me now says they did not see me while signaling or braking then I'll know they were distracted. Or blind. No idea how long these will last but I'm hoping a long time. Tried to put on a short video but it seems I cannot on here.
