Answer 1 Simply put, a relay of any kind is a remote switch controlled by another switch. Relays are usually used to control remote electrical devices which use heavy current [measured in Ampheres, or Amps]. A common example would be auxillary light systems added to a vehicle. The power supply wire would need to be very large to carry the needed current, and would have to be routed from the battery, into the passenger compartment to the instrument panel where a very heavy switch would be required. Instead, good practice is to route the heavy conductor[s] from the battery directly to the lights with a relay installed in between. Then a lighter switch would be installed in the instrument panel with wires from it to the relay. The lighter instrument panel switch and wires control the relay, which in turn controls the heavy current to the lights. This is only one example of the use of a relay. Some others are for powering high current devices such as power seats, power windows, auxilliary devices such as amplifiers, and other sound equipment. Also. to be sure that some circuits are turned off when the key is turned off, a relay will be installed between the "hot" when key is on terminal of the ignition switch to several smaller devices. Therefore, when the key is on, the devices will be "powered up," and when the key is off, they also will be powered down.j3h
Anyopne know the cost of a lighting relay for a 1992 Honda Accord EX ?
you can take thin wires up to a relay then run thicker wires to lights or do you mean a bulb fail relay.

In the 1999 Crown Victoria the LCM, Lighting Control Module , contains the relay for the turn and hazard flashers. This located under the dash.
i cannot fine which relay has turned off my fuel pump and i do not have power to my lights
The headlight relay is integrated into the LCM (Lighting Control Module) located under the dash on the fire wall just above the transmission tunnel.
The Torch Lighting Ceremony was held March 24 in Olympia, Greece. Click on the '2008 Olympic Torch Lighting' link below to see a short video of the ceremony.
No, you cannot use a 50 amp automotive relay with a 12V DC coil to control 12V AC 500 watt halogen lighting. Automotive relays are designed to work with DC power, not AC power. Additionally, the amp rating of the relay refers to its capacity for DC load, not AC load. You should use a relay specifically designed for AC applications with the appropriate voltage and current ratings.
there is no headlamp relay, power is suplied directly from igntion key thru the light swtch. there is 3 positions on the light switch, most of the lighting wires are purple. If your machine has the cab option, you have a set of 7 lighting wires at a dead ended plug under in back of the fuil tank. A good place for a fire to start. I just rewired mine after a nice fire.
Check the light relay circuits for the lighting. Either a relay or electronic circuit is causing the problem of the lights staying on
All fuses (most of them) responsible for lighting are collected in the fuse box which you can find behind coin compartment to the left of the steering wheel.
All lighting is controlled by the LCM (Light Control Module) it located under the dash above the transition bump on the drivers side.
