This genuine Yamaha OEM part is the protective seal designed to cap the rear of the headlight assembly. By creating a weather-resistant barrier, it protects the headlight bulb socket and wiring harness from external elements, which is critical for maintaining consistent electrical performance and preventing premature failure of the lighting system on classic Yamaha motorcycles.
4. Vehicle Compatibility
This part fits a variety of "Golden Era" Yamaha models, including:
| Make | Model Range |
| Yamaha | RD350F / RD350LCF (1985–1988) |
| Yamaha | RD500LC (1985) |
Note: This specific cover is designed for the headlight housings on the RD350 and RD500 series from the mid-to-late 1980s. Always verify your headlight unit compatibility if installing on a different model.
5. Fitment Details
This is a direct OEM replacement for the original protective cover. During installation, clean the rear seating area of the headlight housing to ensure a proper seal. Slide the cover over the wiring and socket until it snaps or seats firmly against the headlight housing. Proper installation is essential to prevent internal reflector fogging and to protect electrical terminals from environmental damage.
