Better lighting on dipped headlamps suggestios please?
Driving through recent flooded patches of roads, & having to dip my headlights using standard LR bulbs I have driven into those areas & had sheets of water wash over the front.

What bulbs & other lights, totally waterproof, could I have to improve front lighting with the headlamps on dip. I don't want to go for expensive replacement headlamps.

Switch the power via relays. So making the cable run shorter and reducing resistance so allowing more juice to get through!

I see. Well, I don't really! Rolling with laughter sorry bigwheels if this hijacks your thread, hopefully this helps your question ...

So what relay would allow what wattage? Standard is H4 55w?

2 x H4's on full beam = total of 120 watts on 12v circuit = 10 amps. Using a 30 amp relay would allow total of 360 watts maximum on full beam.
H4's on dipped would be a total of 110 watts.

Of course fitting bulbs that would allow maximum current to be used are illegal on the public highway in the UK.

The above calculations depend on me correctly remembering my physics from 50 years ago Rolling with laughter LANDYWATCH

So theoretically i could have fitted 100/80 watt Ring rally bulbs in my relayed crystal headlamps, but as that's illegal, it will have to remain a theory.

Does anyone know why my mates 300tdi headlights come on with the sidelight? It's like a softer glow than dip.

It's called dim-dip and was a legal requirement for a while in the '90's. Darren

Thanks. I quite like it, would it be difficult to wire up?

Ickle - yes it would have worked and have been electrically safe to fit 100/80 bulbs with a relayed light system - BUT not for use on the Public Roads. Thumbs Up

Big Wheels - what about under-bumper fog lights for road use. I have a pair of X-Lights from X-Eng fitted on plates below the bumpers so that they don't project forward of the bumpers. Nice light , no glare, do not affect off-roading capability BUT also not expensive compared to some auxiliary lights. Thumbs Up LANDYWATCH
