Tail light issue '81 gs450t

[J86]

My tail light recently stopped working. Brake light still works, it looks like a double filament bulb so I assume there's a wiring issue somewhere. Nothing obvious however, everything looks as it should. Is there a typical failure point for these things? Some place in particular I should check? Thanks much

Have you replaced the bulb? The tail light filament may be broken while the brake filament is intact. If you have a multimeter you can do a continuity test on both filaments.

Check the bulb like GSRick suggests as that one filament will break

It was the bulb, even though the filament didn't look busted. Thanks.
