I saw somewhere on the board here that a fellow rider had done a yellow headlamp.It was very cool looking.I wanted to do one ,but I did not want to run a foul of the plod.........So I contacted the Washington State Patrol in Olympia Wa and asked what the rules are for motorcycles in our state.Your state may or may not have different rules.
The paragraphs below pertain only as far as I am aware to the State of Washington.I thought this would make good reading for anyone interested.
"The headlamp color according to the law must be white.
The standard itself that outlines this is found in a federal standard.
Within Washington Administrative Code (WAC) 204-10, Washington State has
adopted Federal Motor Vehicle Safety Standards (FMVSS) 108 and Society
of Automotive Engineers (SAE) J 578 as the standards for aftermarket
vehicle lighting devices.
The National Highway Traffic Safety Administration (NHTSA) is the
federal agency regulating original and aftermarket motor vehicle
lighting products, including newer technologies. Within the FMVSS 108
standard, Paragraph S7.5 lists the requirements for a Replaceable bulb
headlamp system. Specifically, paragraph S7.5(c) states that the test
requirements of for headlamps are outlined in sections 4.1, 4.1.4, and
performance requirements of section 5.1.4 of SAE J1383 APR85. SAE J1383
section 5.14 states the color of headlamp shall be white as specified in
SAE J578. If a headlight is built to conform to these standards it is
usually certified by the manufacturer as either meeting the FMVSS
standards or the SAE standards. If such certification is not indicated
on the packaging of the lights, it is suggested that you contact the
manufacturer directly to determine whether or not the lights meet these
standards."
I hope this sheds light on this subject and yes the pun was intended.
So no yellow headlamp for me.......
