Recently produced hydraulic pressure switches for brake light activation are often faulty and/or don’t last long.

Hydraulic Brake Light Switch

We decided to use an electronic pedal activated pressure switch as a complement to the hydraulic switch. We sourced the switch from Moss Motors, part number 542-371.

Lucas-type Brake Light Switch

We have modified the wiring harness to accommodate both switches. Trevor Fawcett, in the U.K., fabricated a simple bracket to hold a Lucas pedal switch and we used that as a model for our own bracket – similar, but not the same.

This was our starting pattern (it was slightly modified later), and our bracket after a little bending of a single flat piece of steel in the vice.

After drilling holes for mounting the bracket to two of the 1/4″ – 28 x 1″ bolts holding the pedal box to the chassis and drilling a 1/2″ hole for the switch we we ready to mount the assembly to the car. Following trial fitting we trimmed a bit here and there, rounded the sharp corners and painted it black.

Finally, we connected two trial wires to the switch’s spade connectors and tested the sensitivity of the switch with a test light. The results are depicted in the short Bugeye Restoration Video Episode Seventy-three below:
