Dim lights again

Finally had enough with crappy headlights and so i'm making some upgrades:

1. waterprood russian HID spot lights from the front of a russian tank (honestly)
2. Philips X-treme Bulbs (H4)
3. New wiring from main battery

Having a few wiring "issues" and wonder if anyone can help:

a. Will wire headlights into main batteries with a fused feed and a relay- is it safe to use the current headlight circuit to switch the relay on or off or will this supply too much current.
b. i have 4 H4 bulbs with both dipped and main beam function- can you use both functinos at once on these bulbs or is it only one or the other? would love to have all 4 filaments lit up but i don't know if it will bugger up the bulbs or not
c. is there any reason to wire my spots to a switch so they can be turned off when the main beams are on? are spots unsuitable for MOT?

can anyone help?

James,
1. Relays take very little current so this will be OK.
2. I would not try this, you may break the bulb and you will certainly
be dazzling oncoming traffic, which is illegal.
3. Your spotlights have to be wired so that they only come on with the
main beam, if you switch to dip they must go off.

No gun??

No problem - I've done exactly that. A relay draws about 2 or 3 watts
which is trivial compared to the bulbs.

My experience is that over-wattage bulbs fail prematurely anyway, and
the added heat from running both filaments at once would surely kill it
extremely quickly. The heat might not do the headlight itself much good
either.

You'll fail an MoT if you have more than a single pair of dipped beam
lights active. So if your spots are H4 then, to be legal, you cannot
wire them so that their dipped beams are on at the same time as the
ordinary dipped beams.
However you are allowed "fog lights", which have to be mounted 1200mm or
lower above the ground, and within 400mm of the side of the car. So I
suppose you could argue that these are fog lights so long as you met
those dimensional requirements, but you might end up arguing with Mr Mot
/ Plod.

I have noticed on many cars that using the flasher with the headlights on
low beam illuminates both the high and low beam.
Can't remember how the twin 7" headlights on US spec Jaguars worked, they
might be allowed both low beam on at once or perhaps they were only single
element.
