Re: Front sidemarker question
According to those picture graph's anything in front of the wheels must be yellow & everything behind the wheels must be red. This means I'm not in accordance with the law. I bought a cheap set of 12 yellow marker/clearance lights & mounted them all over the trailer (just for visual effect & night retrieval), in addition to the normal, legal required lighting re: Stop/Tail/Turn (RED) & the front markers (yellow). I think I'd better get those extra markers off or at least wire them on a separate manual switch for the night retrieval. Thanks for the information, I had asked this question last season before I did that & didn't get any thumbs down here. Oh well, BTW: It does really look cool & makes it easier at night under the water.
Not necessarily so. Find FMVSS 108 on the web if you want the full story, here's one site:
http://fmvss108.tripod.com/fmvss108text.htm
As long as you meet the minimum requirements, you can add other lights, so long as e.g., you meet this reg:
S5.1.3 No additional lamp, reflective device or other motor vehicle
equipment shall be installed that impairs the effectiveness of lighting
equipment required by this standard.
(What exactly does that mean? Who the heck knows? I hate ambiguous laws)
I am sure you could mine numerous other regs out of FMVSS 108, having to do with allowable colors, etc.
I would also encourage you to check out your state DMV's regulations on trailer lights; for example, in California, they specifically state that any light within 24" of the back end of the trailer must be red, and anywhere else amber. Made it easy to determine what color could go where.
