I was keeping an old (warped) disc brake and chain sprocket from my ’99 VFR800 around because they looked kind of cool. I knew what to do when I found an $8 clock at the flea market….
Then I went OTT and added some $6 under-vehicle lights from Meritline and hooked them up to the garage door opener.
In fact, the most expensive part was the steel backing sheet from the hardware store. Sigh.
