sapphire cossie.... anyone know what best bulbs to use in front??

 

Are you talking standard or to uprate?

Head/Main beam are H4's, trouble with the latter is if wanting to upgrade you need to consider the age of the wiring, pulling through more power than standard is a reciepe for disaster due to the demand on the wiring.

I used to swear by the auto express award winners, Philips Extreme, and Osram Nghtbreaker, these always scored 1 and 2 respectively in the tests.
Until one day whilst in Thetford norfolk whilst watching out for the zombie attacks I noticed a bulb was blown, on the astra, which previously had used extreme and nightbreaker at different times, I popped into halfords and bought a Halfords Extreme brilliance H4, in a purple box about £20, but was on a bogof offer at time, my god mind blowing difference it made, even though AE didn't rate them!!
These are also in my cossie in the main light, and ring 130watt in the inners.
Previous to this on the astra I had cleaned the insides of the lenses and reflector with correct cleaner, and used HID, extreme(orignal ones were best), silver star(renamed nightbreaker), HID gave next to no output on main beam as was too high in relation to the front, so took it off, the halfords bulbs were by a hell of a long way the best, and last a lot longer too.
I do a lot of night driving, but I would seriously consider HID for the cossie as it has a seperate main beam inner so you could reap the low beam benefits of HID, failing that the halfords ones mentioned would get my vote.
As eluded to you will get a most noticeable benefit by simply using relays and new wire to each light, due to age of wiring, done this on 4 sierra and all improved a lot even with std bulbs.
I use two relays inside each light, one for dip one for main, I kept them seperate so if one dip failed I'd still have the other, I ran heavy gauge wiring direct from the battery live and earth to the relays inside each light after drilling a small hole in the rear cover of each light.

got a set of dip/high hids,39 dollars from the states,great quality and also got a full briaded harness inc relays for 15 dollars.picked 4.5 k i think so as to give white light and not chav blue.

looks very different and daylight to night time difference on the morretes

 

with tabetha on this one, i use osram nightbrakers in the bm but found the halfords extra brilliance ones better in the sierra..

 

halfords extra brilliance it is!!


thnx all

 

ring xenon plus are good and cheap too.or the osram as said

 

Did you use H4-3 or H4-4 ?
