Replacing the Worklight and Takedown Halogen Lamps
Depending on your lightbar configuration, the lightbar may be equipped with either type of
lamp shown in Figure 5.1 below.
1. Disconnect power to the lightbar.
2. Use a large flat-head screwdriver to remove the two 1/4-20 screws that secure the end
dome to the aluminum extrusion (Figure 3.1 on page 16) and remove the nameplate.
3. Slide the end dome off the aluminum extrusion along with any additional domes to
access the PCB containing the lamp.
4. Replace the lamp:
• If the lamp is P/N 810A119 (Figure 5.1, left): Twist the lamp counterclockwise to
unlock it, then pull it out of the socket. Insert a lamp that is an exact replacement
and gently twist it clockwise into the socket until it locks.
• If the lamp is P/N 8107169 (Figure 5.1, right), pull it straight out of the socket.
Align the two pins of the new lamp with the pin holes in the socket and gently push
the lamp into the socket until the lamp is properly seated.
5. Reinstall the domes and secure the end dome and nameplate with the two 1/4-20
screws.
6. Reconnect power to the lightbar.
