Welcome to iRV2.
If the signal light can be made to quit, with the tilt column in a certain position, then have the column in that position when the coach goes in for service, AND, make sure the service writer makes note of the fact the signal light will work if the column is moved.
You have to be sure the mechanic gets ALL the info you can give.
