What does a relay wiring kit do for auxiliary lights?<\/h2>

A relay wiring kit collects the cables, relay, fuse and connections needed to power the auxiliary lights separately from the car's regular lighting. In a standard relay connection, the high beam signal turns the relay on and off, while the current to the lights goes through the separate supply.<\/p>

So there are two things that need to work: the power supply to the lights and the signal that controls them. A set of the correct lamp connectors may still need to be supplemented to work with the car's high beam control.<\/p>

Choose the right connector and number of lamp connections<\/h2>

First check which connector the lamp has and how many pins it uses. DT connectors come in several designs, and DT and DTP are different connector series. Choose according to the lamp specification and wiring diagram, even if the connectors look similar.<\/p>

On Luxtar cable kits it is important to distinguish the connector designation from the number of connections. In DT-3 X2, DT-3 means three pins in each connector and X2 two lamp connections. This does not mean that the kit is for three extra lights.<\/p>

We recommend that you start with Luxtar's relay cable kits and choose the design according to the lamps. Here are three examples for 12 V:<\/p>
