911 3rd Brake PCB
Directions for installation:
Here are boards set up for periscope/snorkel and inside window mount.
Step 1: Open up enclosure and remove bulb.
Step 2: Secure appropriate frames to board.
Step 3: Clean socket if necessary. LEDs do not draw much current and may not break through oxidation on the socket contacts.
Step 4: Connect pigtail base into socket and test PCB.
Step 5: Install boards making sure the wires do not interfere with the board and frames.
Before closing up the fixture, test the light. If it doesn't light up and the bulb does, swap the wires going to the fixture. The wires may have been swapped at a previous time.
