Night sun

I'll proberbly get slated for this but I'm wanting to wire up my 2 halogen spots and four roof bar lights to my high beam ,can I do it through one relay ,does anyone have a wireing diagram

Roof lights can't be used on the highway

Anyway you need to give us some more info:
How many spots (ah just read it again 6 )
Wattage of lamps in spots

I take it that the spots and roof lights are already wired in with their own relays??
If so you can operate both relays using a feed from the high beam circuit

why ?

Where in the road lighting regulations does it say that?
As far as i understand it you can have as many main beam lights as you like as long as they extinguish when you dip your lights.

Roof lights - the law ?

Well thats about as clear as mud

Seems nobody can find any reference in regs for position or wattage of optional headlights.

Having said that 100w bulbs are sold as 'not for UK road use' but the regs seem to state that they can be anywhere so long as they operate through the dip switch and have an illuminated light to warn when they are on

I remember reading somewhere that they must be forward of the axle and a max of 55w - if that isn't correct - then who knows??

I do know 1 thing - switch on your roof lights on the motorway and try and see where you're going

There all 55watt halogen ,the ones on the roof bar are more a work light option so may put them on a separate switch

Everyone seems to know this but nobody can find it in the lighting regs.....I've always thought the same

Ive read it too somewhere? But cannot find anything in the regs regarding position or wattage?
Thats why I questioned it.
I almost dazzled a copper going round some pretty badly flooded country lanes the other week stopped for a chat as he wanted to know how bad it was where id just came from. Never said anything to me about using mine.

When i asked my MOT tester he looked it up and it just said they had to be equal distance and height but didn`t specify what the height was. as far as he was concerned my roof lights switched with main beam were perfectly legal.

If I run a positive and negative to my roof bar via a switch and inline fuse do I need a relay?

depends how much the switch can cope with and were your taking the feed from,relay is used so you can use lesser rated switch and wiring in the dash etc with main feed for light taken from a decent battery lead ,starter ,etc

This may answer the use of extra lamps.
Section 27 at the bottom under other lighting.

The Road Vehicles Lighting Regulations 1989

Would have thought if they come on with high beam they would need to have a set beam pattern and be at correct hight
