Dipped beam to stay on with high beam

rlj86 · Oct 17, 2011

Has anyone done this, if so how do I go about it? Be better for me on the land. Is there a reason why they switch over?

they shouldnt stay on together.

further to that, you are likely to blow fuses, overload the wiring and, prospectively have a fire

Ah right, they do switch over, wanted them to both to stay on when main beam was on, no worries. Cheers

+1 - Which is why they do not both stay on

better to fit some additional driving lights with a wide angles beam

To be honest, you will get more light where you want it but fitting Aux lights - plenty places to fit them

Some people do modify the wiring so they can both come on safely.

Benefits - better illumination of the road directly in front of you.
Drawbacks - lamps (bulbs) don't last as long.

You need to setup a circuit for a relay that is switched by the full beam circuit, this then feeds the dipped beam circuit too via a fused live supply (directly from the battery would be fine).

The negative needs to be replaced with a cable rated to at least 12 amps (built in saftey factor of 20%) I would go for 15 amps. For this, I'd just undo the old one, and run 2 new ones to a good earth point or better, the battery. This is a common modification to do anyway as it ensures the headlights get a good earth and work at full capacity.

I am looking at fitting either a 4 or 6 light bar across the the top of the screen but was looking at this as a quick n easy fix for now till I get round to doing light bar. Thanks for your input guys

Why? There is no need. Just do the light mods as described in the FAQ section and fit +90 or +120 bulbs in the headlights.
Roof lights just give huge glare down the screen and over the bonnet
