Daytime running lamps are optional lamps fitted to the front of a vehicle to make it easier to see in daylight. They have a low light output and are not bright enough to illuminate the road ahead of the vehicle.
Fitting requirements
You can fit up to two daytime running lamps to your vehicle. If your vehicle already has two daytime running lamps as original equipment, you can’t fit a second pair. On some vehicles, daytime running lamps operate as a function of the main beam headlamp.
Daytime running lamps should be wired so that they automatically switch off when either the dipped or main beam headlamps are turned on.
Daytime running lamps must be white or amber in colour. When purchasing daytime running lamps, it is your responsibility to ensure they meet approved standards and are designed for that specific purpose. If in doubt, consult a vehicle lighting retailer.
On the road
Daytime running lamps are normally designed so that they turn on automatically with the engine ignition, and turn off when the dipped or main beam headlamps are switched on.作者: 喜马拉雅大山猫 时间: 2013-3-29 20:26:34
