I'm not completely sure for a 93, but if it is the same as my 98, that little red light is you oil light. Either your low on oil or something isn't working right.
I believe the only colors available then were red blue and black..
The battery is under the saddle. The red cable goes to the terminal marked positive (+) and the black cable goes to the terminal marked negative (-).
When riding at night without lights, the red light doesn't destroy your night vision you ole caped crusader, you!
The red key light is for a security system (if your bike has one installed). When the red key is blinking, the security system should immobilize the starter.
When these light stay on its an indication that something is wrong and needs to be serviced.
If it's red you'd better not be driving it. If it's amber have your mechanic check it out ASAP.
The model 90 was not a Red Ryder model, it was the Sportster model made from 1973 to 1978
he wears a movado sportster
Get your charging system checked out as it sounds like your alternator is going bad or the battery is shot.
I Have the same issue. Red Light on the speedo stays on. It seems to refer to an electrical problem. Ive discovered that my brake lights dont work sometimes. Could be the cause. Im off to HD today. 2012 Dyna FXDWG
Red light shining on an object that reflects primarily red light will be red
