I installed a Signal-Stat aftermarket signal on my 1953 PU with no problems. My "new" 1954 already had a similar unit installed by a PO. It works fine, except for one thing: the middle red light is always lit up. On my previous one, it only was on (and flashing)when the 4-ways were engaged.

Is this normal? If not, is there an easy fix without tearing everything apart? Thanks!!
