I've read that if you paint the inside of the bucket white instead of silver/metallic/no paint it's more reflective and in turn brighter. Is this true?
FWIW, I tried these https://www.amazon.com/gp/product/B07N1JQJZZ/?tag=atomicindus08-20
I have the white ones in the parking lights and they work okay but sometimes they drop out, probably a grounding issue. I tried the red one in the stop light but the 32cp bulb was brighter so I stuck with it. Those bulbs are advertised at 450lm but they weren't bright enough for me.
Is anyone aware of a 6V LED bulb suitable for brake light use ??
I have one on my truck, 6v positive ground. The one I have there is a very noticeable difference. Sorry can not quickly find the info on them. Can look more if interested.
They are a plugin direct replacement in for the existing stop lamp. I also converted the tail lamp to LED
What has really helped though is I installed a LED 3rd stop strip on my truck, on the tailgate. People really notice it, and do not come up behind me close when braking. I highly recommend using one. People are not used to looking for a small round brake light blended in with a license plate. If installing on a car my recommendation is to install it more directly in other drivers line of sight, instead of in the rear window.
Do you have a picture of adding the 3rd stop strip on your tailgate. Was thinking of doing something similar, or adding in rear window.
