Quick question about headlights....

[mrizvi66]

I want upgrade the Headlight Bulbs. I have an H4 system.

If I order the H4 55/100 Watt Replacement Bulb or the H4 80/100 Watt Replacement Bulb, I will need the High Power Headlamp Relay right?

Can some one clear this up for me.

Thanks

do a search for big info..........Ron

I recently did the search on the same topic and came to the conclusion that if you use a higher wattage bulb, use relays. Even with the stock system, you are better off using relays as they make things easier on the car. I just ordered relays from Mark Sucros and for the price they are very well put together.

our lite wiring was designed for 45w low beam...........Ron

I put the 80W/100W bulbs in my H4's. When I did, I put TWO relays in. One for the LOWBEAM and one for the HIGHBEAM. I've never had any issues with either.

I also did the dual relay bit from M Sucro and it couldn't have been easier. Only $20 too with great instrutions.

Relays. No-brainer.

I think the relay kit (two separate relays for high and low beams) Marcus provides is sufficient for up to 100 watts (someone correct me if that's wrong), but the lamp-holder may not be. There are several stories on this board (and Rennlist) of these lamp-holders "slagging down" if used with high watt lamps, heavier duty lamp-holders are available, try this link for the lamp-holders and additional information on lighting up-grades. . Your wiring from the relays to the lamps will also have to be up-graded, it's much too small for 100 watts, be sure to up-grade the grounding (earthing) side of the lamps also. Be sure to fuse these circuits approriately.

I'm glad you did the thread, thanks.. I'm a little hung over, and didn't have the energy to reply to a flame from someone whose lamp sockets haven't melted YET.. the melt is routine on the 80w low.. sometimes it has started fires, but that's not routine.. and Warren suggested that you could just remove the lamp socket completely and draw a little diagram inside the lamp hole.. I use the ones from Dan Stern, per the site that Jerry posted. and BTW, I run 130/100w, using 2 75amp Bosch relays.. but the 30amp Sucros are OK.. I just wanted bigger relay contacts and amps because I had a bright idea to run both high&low filiments on the high switch.. it worked great for a few minutes till the lamp inner ground melted.. so big darkness on both lamps on an unlit road .......Ron

All,

A bit late on this thread, but I have had a few questions via email lately, so here are my $0.02. The comments about the headlight sockets melting sound valid. I have been running 55/100s for 15 years w/o problems, but I do normally use only the lows. The relay kit I sell is good for 130W highs and has been using 40A relays for quite a while. The other comments about upgrading the factory wiring are good too... I think that I will add a note to the directions about making sure that the factory wiring/sockets are in good condition.

Thanks,
Marcus

i'm running the same bulbs/euro h4's that ron does.....but i have 4 relays total (30/40 amps each).....one for each filiment......i also upgrade all my wiring to 10ga. which is overkill but DAMN are these things bright

One of my cars had the H1s set so both high and low would come on at high. I didn't like as it puts light up close when you want your attention focused far down the road.

sorry to hear about that Randy, LOL.. my 100/130w together turned nite time into day time.. if I ever get my act together for the valence fogs.. I'll have 130w low beam instead of fogs.....Ron

maybe you could install a rally light setup on the hood for your next bigride.........they could help keep the cougars away (the cat, not the car )

Sorry to get off topic, but...

I don't think ANYBODY knows the words to that song, everyone I've talked to is like ......"what do they say there...douche??"

Can anyone here solve the mystery?

[pwd72s]

I always thought it was: "Wrapped up like a douche in the middle of the night".. Perhaps a call girl could clarify things here?
