Verify relay compatibility

The selected three-prong relay is not for custom LED lights. Confirm the installed lamp load and connector arrangement before buying it. A changed lighting circuit needs its own compatible flasher rather than a relay selected only from the motorcycle’s original year.

Check the lens mounting pieces

The gasket matches the specified stock-type signal-lamp family, and each screw pack contains two lens screws. Compare the lens and housing before placing the order. Keep package quantity separate from the total number of lamps you intend to service.

Ordering questions

Can I use this relay after fitting LED signals?

No. The featured relay explicitly excludes custom LED lights. Identify the converted system’s requirements and choose a compatible flasher instead of using this conventional-lamp option.

How many lens screws come in one set?

One set contains two screws. Count the screws needed across the lamps being repaired, and confirm the housing matches the listed stock-type design.

Will the gasket fit a custom signal lamp?

Its application is tied to the documented stock-type lamp and lens family. Compare the actual gasket profile and lens mounting arrangement before ordering for a replacement or custom lamp.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
