Exactly What I was looking got

A friend of mine recommended these switchbacks after both my head light bulbs went out at the same time. With these guys I never have to worry about driving blind. These guys are powerful and hold up

Switcbacks, rear strobe lights.

These are amazing, simple install like you would a regular bulb and definitely increase vision and distance while also adding a nice light while driving at dark. I want to purchase the rest of my bulbs from this company because it is just an easy and better upgrade from the halogen bulbs. A major plus is that there is no hyperflash even with my vehicle being a 2010! That really surprised me.

What are CAN Bus LED Bulbs?

when we say CAN Bus LED bulbs, they are the easy plug-and- play LED lights bulbs which are made specifically for the vehicles built-in CAN-Bus system. These bulbs work with your vehicle's advanced computer system, so when your vehicle's computer reads them, they respond back correctly.

To see if your vehicle operates with a CAN Bus system, simply remove the bulb you're looking to replace, start your vehicle, and if you have a "Bulb Out" message on your dash you have a CAN Bus system.
