Yes these LED lights put out a bright light. We mounted them a cooler carrier we had made custom for our trikes. The one thing I found frustrating was each type came packaged differently and had to buy other hardware to mount on carrier. It was hard to find hardware that fit. One type came with screw & self-locking nut which was the prefered hardware.

YEA, I BOUGHT THESE FOR THE REAR OF MY BLACK TRIKE, FIVE ON EACH SIDE, RED LIGHTS FOR VISUAL PROTECTION FROM REAR CRASHES- YES THEY ARE BRIGHT ENOUGH- GREAT PURCHASE FOR ME ,EXCELLENT BUY.FOR ANYONE. SO GO AHEAD, MAKE THAT BIKE DIFFERENT. I DID & AM DOING. NOT TOO MUCH THO !!!!!!!1

I have used these in combination with the step lights for accent lighting. Easy to mount and work with and they also put out good light.

These little guys kick out a lot of light.

Use them as an accent and they look great.

YOU WILL BE AMAZED AT THE BEAUTY AND BRIGHTNESS OF THESE LITTLE LIGHTS. I BOUGHT 2 SETS OF RED,WHITE AND BLUE AND AM WELL SATISFIED.
