Coy Nikolaus
Direct fit to my 1991 caltrans trailer.

Fit perfect. Colors match and was nice and bright. Easy install. Good material. I've used nilight light bars and they worked great. I happy with this brand regardless to it being Chinese made. It's a good quality for the money.

Edward Taylor
Great light, easy to install, however it is a tiny bit smaller than what we replaced.

I liked the brightness. It was easy to install and plug into existing wiring. However we had to reuse the old rubber circle from the original P30 step van as the new black rubber circle was just a little smaller than the original.
