Check your factory bulbs for fitment

I messaged the site due to it saying the bulb wouldn't work for my 22 Hyundai Elantra N-LINE, but the bulb that came out of the car was part number identical to the one on the site. I was told that sometimes trims aren't 100% updated but if the bulb is the same part number it will work. These worked on my car perfectly. They were a tad larger than the bulbs but no modifications had to be made. I am happy. These and the T10 LEDs that have the red shield work fine in my car without dash issues. I do recommend if you have the car I do, to get the CanBus blinker lights. The front were 2357(listed as 1157) and the rear were PY21W (both in amber). Sign up for emails and subscribe to the site, I got a15% off discount for doing this) This can be a frustrating and confusing purchase but I recommend Alla Lighting and have had them in multiple cars and have only had one go dead, Alla Lighting replaced it for me with no hassle.

While everything I said is absolutely true, they offered me a pair of a T10 LEDs for my review. They didn't ask for a 5 star review. When I purchase something, I like to know this type of thing. Happy modding!

Great Bulb for Cargo Lights

Perfect for cargo lights on Toyota Tundra. Hope they hold up. I bought these because they state they are waterproof - get a little moisture in the cargo light housing and needed lights to be waterproof and more sturdy. These lights feel solid and I believe they will last much longer than previous LED's and standard bulbs.

Simple and Great Product!

Fantastic Product!

These reverse lights are awesome! I bought a 2020 Tacoma here a few weeks ago and I was looking for a suitable replacement reverse light as the halogen bulbs have always seemed boring to me. Item arrived on time, as described, well packaged, easy to install, and for a great price! I will be looking to Alla Lighting for all my future automotive LED purchases!
