Huizen 10-30V CanBus Error Free 39mm Festoon (6418/C5W/3910) LED Light Bulb (White) Replacement for Map Dome License Plate Lights - 6-SMD 3030 Chipsets - 2 Yrs Warranty (Pack of 2)

I've been trying to compare many different 921 replacement bulbs for my camper, and the Huizen 360-Degree are the brightest I have found so far, but I am still a little disappointed. They are advertised as 1550 Lumens, but I am not so sure. The units I purchased were described as warm white, but they are clearly more like a cool white. I have included pictures of these compared with the stock 921's and next to the GRV T10's that are supposed to be 420 lumens. I also have a picture of the PESIC T10 921 LED's compared to the regular 921's. Unfortunately, not all of the pictures are in the exact same conditions, but you get the idea. The Huizen are the brightest, followed by the GRV's then the PESIC. The Huizen's are probably slightly brighter than the standard 921's. The GRV's appear to be the highest quality as they are actually in an enclosure similar to a regular bulb, and they are cheaper than the Huizen's. I paid $6.48 ea. for the Huizen's, $5.14 ea. for the GRV's and $0.70 ea. for the PESIC's.

Said they were replacement for what I needed. But they’re too small.

they looked great for a week then stopped working don't waste you time

I like how bright they are, it illuminate very bright at night.
