1982 Honda CB900F · Turn Signal Service Buying guide
Separate flashing faults from lens sealing
An incorrect flash rate, a broken lamp and water behind a lens need different repairs. Check the bulbs and wiring before choosing a flasher, and identify the actual lamp housing before ordering its gasket or lens.
The relay replaces 38301-415-671 for the listed later-model application and explicitly includes the 1981–82 CB900F. Its description excludes custom LED lights. If the signals were converted, identify their compatible flasher requirement rather than ordering by the motorcycle year alone.
Check front and rear lamps independently
The listed front lamps use three wires and the rear lamps use two. Black and chrome finishes do not change that front/rear distinction. The gasket matches the stated lamp family; a different housing or an LED conversion needs its own electrical and sealing checks.
Turn Signal Service questions
Will this flasher work with an LED signal conversion?
No. The listed 12V/23W three-prong flasher expressly excludes custom LED lights. Select a relay compatible with the installed lamps and wiring, and check the cause of an incorrect flash rate before replacing parts.
Can I use the same complete lamp at the front and rear?
The listed front assemblies are three-wire units and the rear assemblies are two-wire units. Match the position, circuit functions and mounting; a similar housing or matching finish does not make them electrically interchangeable.
Will a new gasket fix every water leak behind the signal lens?
Inspect the lens, housing lip and fastener points too. Gasket 33406-431-781 is matched to the specified signal family. A cracked lens, distorted housing or different aftermarket lamp requires its own repair.
