H4 headlight replacement

Recommended Posts

Hello to all..

I've seen that Motorsport Auto offers H4 lights to replace the stocks set. Also they offer Xenon light bulbs. My questions are: 1) Has anybody used these or anything like them? and 2) How are they compared to the new fancypants bright white set-ups I've seen on some of the newer cars coming out ? I'm looking for an updated look as well as better visibility at night:ermm:

There is a member here and personal friend of mine who can answer all of your questions, including power source, relay and switching issues for these new light systems.

I have used both CIBIE Z beams, and the Hella's with great joy and success. Just make sure to replace the headlight switch and re-work the fuse box...if you are gonna use High wattage bulbs.

That's what I do too! I wouldn't do it if it were annoying to others, but I have checked several times and my hi-beams don't come anywhere NEAR the back window of a Ford Expedition.

Yeah, I figure the high beams in my stock headlamps aren't even as bright as most modern low beams, let alone Xenon bulbs. That coupled with the fact that most other cars' driver's compartments are much higher than mine, I don't feel it's an annoyance to other drivers. I have yet to have someone flash me for my headlamps being too bright.

edit: poor grammar.

My zeds head lights are pretty bloody dim too. Moulded into the front glass it says they are Hella H4's. The aren't aimed properly which is part of the problem, but even if they were they are still dim as.

Should the H4's be pretty bright?

Maybe the wiring to them is inadequate, therefore not getting the voltage they need?

Just remember that the wiring for the 240 was designed with the older 55W/45W lights and not the newer 100W/90W. By doubling that wattage you are increasing the amount of current and therefore load on the wiring. If there are ANY flaws (i.e. resistance points) in your system you WILL cause problems.

go the upgrade!! it helps tons!

I've upgraded to the H4 kit.. then installed all wiring relays.. then put in the ultra white bulbs.. visibility is excellent and I'd be lying if I didn't say I think it looks pretty mad :D

btw - here's an idea of the brightness.. (that aint my high beams)

Arch, what H4's did you use?

I picked up some spare Hella H4's originally sitting around Zworx, they said they were the right ones, i went on their word.

If yours are hellas do you have the model # and a rrp

thanks

Do you mean the actual H4 lighting assembly or the bulb?

the bulbs are from a volvo dealer (uber mates rates - autobarn jack the price of those things up so much its crazy! I got a set of two for like $10)

the assembly I can't remember.. Can check when I get home but I dont think they're hella..

On a 240z parts car I bought.. it had Hella H4 assemblies (as in the cone, glass, etc) but I've long since thrown all that out (they were cracked, etc)

Have you tried the ones you got yet?

If you fit the halogen bulbs it is a good idea to fit a couple of relays (5pin) one for high beam and one for low.

I havent tried them yet, as I dont have an engine or electrical system :)

I mean the assembly I guess.

yeah - an engine, etc always helps :D

hehehe

The benefits over the standard sealed beam lights are more then worth any effort involved in putting in at least just a H4 kit..

I've done the conversion to both my Zs, but have taken it further with my current one installing the relays, better bulbs, etc..

the white lights may not suit everyone.. but the standard H4 upgrade alone is well worth it!

I assume the relay connection is just battery, headlight switch and headlight? Hide it somewhere and tuck the wiring away as neat as possible?

I might try and cut and shut the instrument panel/switches from the dash of whatever front cut i choose into the zed dash, should make it extra fun too.

This is for those that have done the relay conversion for upgrading your lights:

Where di you get the relays? What brand, style, part numbers?

I'm having a bit of a hard time finding the relays to even get started. Seems most of the local parts houses don't carry relays (other than turn signal or wiper relays). If you ask them, they just look at you :cross-eye !

Anybody have any suggestions where I could go? Online stores even?

I have a set of the Hella H4's sitting on a shelf because I already melted a low/high beam switch a few years ago. And I hate dim lights!

Have you tried looking at Radio Shack? I don't know that they still carry them for certain, but that would be the first place I would check.

Our local Radio Shack sure scaled back on carrying electrical components. All they seem to care about these days is selling TVs and cell phones.

I have the H4 conversion from MSA. I believe that they have three different types. I have the non-DOT approved set with the pre-mounted city-light bulb. I'm pretty sure they came with a 55w/45w bulb, and the guy at MSA suggested that I didn't run anything higher. They are a lot brighter than the original still.

the h4 conversion is really easy and well worth it just for the fact that you get the ability to change globes and not complete head lights when you blow a globe

All you have to do is remove headlights put in new h4 cone and glass with new globe i use 100w /65 w

fit relays in the circuit to reduce load on switches (well worth doing for the age of the switches anyway)

Have tried th new ultra white globes but they where cheap chinese copies and apart from being white light i thought they where dimmer than the standard h4 globes.

I agree the H4 conversion is definitely the way to go, but I want to run the higher wattage bulbs. I want to make sure that the other zombies in their boxes-on-wheels see me and don't hit me! So, that means I need the relays.

Mayhem, I have already been to that site and yes it has a wealth of information, except where to buy relays, unless you buy from them. And since I'm a mechanical person on a shoe-string budget, I have a hard time buying things outright that I could make on my own.

Still the question stands....(other than Radio Shack, which I will check out today) Where can I buy automotive relays?

They dont have to be "automotive" relays, they just have to suit your current/volatge requirements. Im not sure about names of stores in the states, but there should be a wealth of electronic component stores.

You should have an equivalent to something like this:

http://www1.jaycar.com.au/productView.asp?ID=SY4068&CATID=&keywords=relay&SPECIAL=&form=KEYWORD&ProdCodeOnly=&Keyword1=xxxxxxxxxx&Keyword2=xxxxxxxxxx&pageNumber=&priceMin=&priceMax=&SUBCATID=

and from my guess the maximum current a headlight will draw will be under 15A@12V, as arent they usually under 160W??

I know ADVANCE AUTO sells them right off the floor, but drunkenmaster is correct. As long as they fit the requirements they don't have to be "auto relays".

drunkenmaster, nice link.:D

What is special about the ones labeled "automotive relays?" Are they water resistant or something or are they just a grade that is commonly used in lots of automotive applications?
