Turn Signal Lamp: Description and Operation

When Operation Is Normal
- When the ignition switch is switched to the ON position, battery voltage is applied (via the multi-purpose fuse No. 4 and hazard switch) to the turn-signal and hazard flasher unit.
- When the turn-signal switch is switched to the LH (or RH) position, Tr (within the flasher unit) is switched ON and OFF repeatedly. Then the contacts of the relay (also within the flasher unit) repeatedly switch from ON to OFF, causing the turn- signal lights and turn-signal indicator light LH (or RH) to flash.

If One Bulb Is Burned Out
- If either of the turn-signal light bulbs is burned-out, the resistance of the turn-signal circuit as a whole increases, resulting in shorter ON and OFF intervals of the Tr and a higher flashing rate of the lights.
