A circuit for indicating the failure of a turn-signal indicator lamp of a vehicle is effective even when the signal indicator system is not in use. A resistance 5 or 15 bypasses the operating switch(es) 11A, 11B, 16 of a lamp 7 or 13 to pass a small monitoring current through the lamp. A tell-tale 3 or 13, connected either across the monitored lamp or between two monitored lamps, is illuminated via the resistance should a lamp fail. <IMAGE> |
