Changing a room light bulb:
1. Remove the front panels enough to get to the bulb.
2. Replace the bulb in the socket and make sure the new bulb is screwed in tight.
3. To put the panel back in, flex it and pop it in to the slots.
How to change a LED hazard light:
The Super Bright light emitting diodes should last for a very long time. But if necessary to
change the
red LED lights it is best to go in through the front panel because these lights are
glued on a clear sheet of plastic behind the room graphic color panel. There are three sheets of
plastic on the front of the house; the
clear front panel , the color panel , and the LED panel .
The LED panel has clear tubes that hold the LEDs.
1. Remove the front panel as instructed above. Now you will have access to the LED panel
and you can remove the LED that is burnt out. Important: Only pull the LED panel out
enough to get to the LED that you need to replace because if you pull it too far then
many of the wires going to the LEDs will pop off and you will have to put them back
on.
2. Pull the brown connection off of the LED. Note that the LED has a long lead and short
because it is polarized.
Note: The connector has yellow on the long lead of the LED, and blue on the short.
3. Pull the LED out of the clear tube carefully to avoid popping the tube off the panel.
4. Replace the LED and put a little hot glue on it to hold it in. Connect the brown connector:
LED Long Lead - Yellow wire
LED Short Lead - Blue wire
5. You can give the leads a little bend to keep the connector from slipping off.
6. Pop the front panel tabs back in and screw the back cover on.
You can get replacement bulbs and LEDs from Robotronics. You can get the LEDs with or
without the yellow/blue wire going back to the circuit board.
