Give it a shot
The Alla switch back LED lightbulbs installing were easy and it works good on 2007 Dodge Ram 1500 with aftermarket headlights. I made sure them work correctly with turn on engine before put them in headlights units. Brightness is good and nice white and turn to amber then back to white. It takes less than a second for switching color but I don't think it's big problem. My old switch back last long years so I give shot to this.

Bright
Switch from white to orange makes the front of the vehicle look great. Easy to install. The white is bright like fog lights

Phenomenal, finally a brand that WORKS
You have no idea how many bulbs I've gone through trying to find working ones that wouldn't hyperflash. These are a+. I was even able to remove the nonsensical giant resistors from my wiring, these bulbs didn't need it and had perfectly working flashing and switches back to white when not turning.

Very bright.
Actually ordered these by mistake but I’m pleasantly surprised. I intended to order ones with the built in canbus system. These do cause hyper flash but install some resistors and you’re golden. Amazing deal for the price and I’d buy them again.

Need a load equalizer
I’ve always liked the switchbacks. Installed a load equalizer and they work and look great

stay away
doesn't fit in a 3157 socket, during installation the LED fell into the housing and needed 2 hours to remove the whole housing to remove this crappy "OEM" replacement

3157 bulb hyper blinking 2005 Chevy Tahoe
Very bright but 3157 bulbs we’re hyper blinking in my 2005 Chevy Tahoe. I bought a bulb with a resistor inside instead of putting resistors in the wires, but that might work to fix this error.
