uprated headlight loom

drill holes in the block of resin round the relays worked for me.

would put link to website but i was pissing around with it and sort of accidenly killed it this afternoon

my overkill version,  usefull comments welcome as currently motivated to poke site with sticks

be interesting to see how your H4s last with both filaments on, heard reports they dont like this and die quickly. also took me a while to figure out your diagram till I realised that was just for 1 side! Proper overkill 
With mine I use 3 realys, 1 per side for dipped and 1 for main. never bothered with fogs as they dont do much anyway, but I might experiment with this and see what kind of difference it makes.

Oh, and are those green relays from french? look familiar from my citroen ax fixing days (my girlfriends car)

[danny_p]

the relays came from the big bucket "o" relays seen those coloured ones in french cars but i think these ones would be Rover ( shock horror )

i was in a modular desing mood when doing this loom hence 1 module per side,  think the only reason i included the fogs was because i chould and they may help light the hedges. 

the intrestig thing is the H4 bulb life, i think it massivly depends on the bulbs you have fitted.  i've had nightbrakers wired up to double fillament in the past and there life expectancy was proably reduced but still accseptable,  some  cheep  bulbs may object quite strongly tho i've had them fail very rapidly but they dont seem to last very long when used normaly,  the beating there getting from the roads round here and my suspention proably din't help tho

its just one of those things that 'they' say, not something I've ever looked at myself. not really felt the need to as quad lamp grille does damn fine job at full beam at any rate

[danny_p]

quad light is much better than singel for night driveing.  do get a fair bit more light with loom upgrade tho,  nightbraker bulbs make a massive differance as well tho even with std loom

[JMallows]

I used Maplin relays also. I have five relays, one per side for dipped and full beam (again one box for each side), and then one for the fog lights, which make a very big difference to me. I used to have the quad lamp grille, but now have single and big bumper fogs, and this is much better i find.

well done the dipped beam tonight could see a noticable differnce even in the day light so another cheap worthwhile mod me thinks

i started of with 12.50 volts and now have 13.79 volts didnt think that 1 volt would make much difference sopose tonight il be able to tell better

the light output of  a halogen buld dosent have a linear relationship to voltage

wat is it them m8 amps ?? or somethink else
