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.

extremely well made bulbs, they work great. White when lights are on switch to incredibly bright amber when signals are activated. no resistors to worry about. no hyperflash. safety and looks have been greatly improved. would highly recommend. well worth the price!

Super Bright!

These are by far the brightest turn signals on the market. Plug and play, no hyper flash as promised and fast shipping. Do not waste your time with any other brand, this is what you are looking for. See for yourself, you will not be disappointed.

Light is too big

The light is too big, does not fit inside the housing. Very disappointed because it works well I just can’t install because of this problem

3157,switchbacks,backup lights..

Installed on a 99 F-350 Super Duty. Although I still had to use resistors for the blinkers.. I am very happy with my purchase. The turn signals and brake lights are bright and the backup lights are super bright. I do however wish the switchbacks we're just a little bit brighter on the white light. But the Amber is super bright. I'm very very happy with my purchase. These guys were fast at shipping and answering my emails. Five stars for all transactions. These guys are top-notch I highly recommend.
