RX7 Headlight Circuit Fix

High Beam Latch Circuit

Back in the day when Mazda was building the RX7 they apparently thought it would be really clever to make their high beam dimmer ECU controlled instead of making it a toggle switch like just about everyone else in the world.  Well it didn’t look so clever to me when this dedicated latch circuit failed on me, leaving my vehicle without high beams.  I threw together a little circuit that uses a T-Flip Flop to toggle the Dimmer Relay.

Difficulty : MEDIUM
Time: 1-2 hours (including wiring)
