How does the DIP switch work on a headlamp?
1 When the head lights are switched off, triggering the relay causes the main beam to flash for as long as you hold down the switch. 2 When the headlights are switched on,the relay then acts as a dip switch with each momentary activation of the relay causing the headlights to alternate between dipped and main beam.

When to use high beam or low beam headlights?
Basically, when you need your headlights to be as bright as possible, you select the high beam option. Alternately, when you need a dimmer headlight, you select the low beam option. In afterhours driving situations where there’s little or no light around, the high beam option is essential.
Why are my LED lights dim when I turn them on?
When electrical loads turn on and off in your home, this change in voltage levels will cause the LED lights to occasionally dim and or flicker. Certain appliances in your home require more power when they initially turn on. The name for this is “surge wattage”.
Can a dimmer be used with an LED light?
Dimmer compatibility with LED lights: Some light switch dimmers may not be compatible with all LED lighting. Check to be sure the dimmer switch is compatible with the LED light bulbs. LED light compatibility with dimmer switch: Some LED light bulbs are not dimmable.
What is causing my headlights to be dim?
Corroded Ground Wire: One of the most common causes of dim headlights is a corroded ground wire. Ground wires connect the bulb circuit to your car’s chassis (which serves as the ground itself).
What is the problem if head lights are very dim?
The most likely cause of a dim headlight is a bad bulb. Headlights don’t blow out, they dim over time, and rarely do both headlights dim at the same rate. A bad ground can result in lower than required voltage being delivered to your headlight, which has a particularly pronounced effect on halogen lights.
What causes headlights on a car to dim?
Common reasons for this to happen: Corroded Ground Wire: One of the most common causes of dim headlights is a corroded ground wire. Discoloring Deposits: This is particularly common with halogen type light bulbs. Bad Alternator: Another very common reason to see dim headlights is a failing alternator.
When do you dim Your Headlights?
Drivers are required to dim their headlights when approaching an oncoming vehicle within 500 feet or when approaching the rear of a vehicle within 300 feet.
Why do you need a relay for a headlight switch?
By using a relay we move the high current switching away from the headlight switch so that the switch only sees a small current – in the range of a few thousands of an amp. This solves part of the problem. You will need two relays – one for low beam and one for high beam.
How many amps do you need for a headlight relay?
If you wish to do so, you can install 15 Amp fuses in each lamp beam circuit. These fuses should be placed adjacent to the new 30 Amp fuse. Make sure the connections are clean, tight and covered with white grease. So, now you know what the problem is and how you can fix it. OK, if you really insist, more “While you are at its”.
Where does the fuse go on a headlight relay?
The two headlamps are connected together, as normal, and taken to Pin 87 of the relay. Pin 85 goes to ground while Pin 30 goes to the new 30A fuse. If you wish to, a separate wire from the fuse can be used for each relay and can be colour- coded the same as the corresponding headlamp wire. This is what I did.
