Switch backs

The bulbs I ordered were too long for my light housing, Alla lighting found a replacement to fit my car and exchanged the bulbs. Great customer service and support.

Jon F.
Vehicle's information: 2008 ram 2500
All lights on 08 Ram 2500

Light brightness wise are nice but the low beam turn off while driving so I have to keep it on high beam! That’s the only complaint I have!

Switch back led bulbs

So easy to install, it was just plug and play and so easy to find, every light on my truck is alla

Csaba K. (Canada)
Vehicle's information: 2014 Mercedes Sprinter
Finally the look of a modern vehicle

I purchased these for the Sprinter, and the look is way better than expected and the safety is much higher. The brightness of the white is fantastic from a parking light perspective, and the switch to amber is noticeable to on-coming traffic. Added power resistors to stop the hyper flash. These are not Mercedes CAN-BUS defeating, so as long as you are okay with ignoring the dash warning of burnt out bulb, they will meet your needs.

HARLAN C. (United States)
Vehicle's information: 2016 Newmar Dutch Star
Great Customer Service

After returning from a long trip to Texas, I noticed we had a backup LED and a left blinker not operating at full brightness. Since our Newmar Dutch Star came with ALLA lights, there's only one supplier I needed to place my order with. Within a few days, I had both replacements.....but had a problem installing the backup LED in the socket. No problem with ALLA to the rescue.......with the customer service team determining I ordered the incorrect bulb. So I sent them back and got the right LED's returned. Thanks for the assist and great customer service!

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.
