    I understand your point but with only one headlight you don't have as wide a spectrum of light.

    The Honda PCX has dual headlights that both come on all the time that can't be turned off that's all I want to achieve and plus it looks better.

    In England full beam is only used when you are on an unlit road with no other traffic when you see a vehicle approach you switch it off.

    Thank you for your help and concern. hopefully you will continue to offer suggestions in my modifications thread when I start it

    In asking for both lamps on in low-beam position, I think you're missing a point. There is only ONE FILAMENT in each bulb, so there is no difference in the light intensity for high or low beam - they are either on, or off. By wiring both to be on in high beam position, you can drive all the time on high beam, except at night to avoid blinding traffic ahead. The way they are aimed, you NEED the single lamp at night in traffic. I don't operate much in the city, and I haven't honestly asked someone whether my headlights are annoying during the daytime, but they're both on all the time and I haven't had any complaints from other drivers or law enforcement.

    Thanks for the info so your saying that in terms of the light intensity there is no difference between. I don't actually know as I've never looked myself just wasn't happy with only one being on. I'm going to change the bulbs to a more white colour as they look crisper.

    How did you wire yours like on the beginning of the thread ?

    Thank you

    Correct - no difference in light intensity between high and low beam, but high beam lamp is aimed differently, and as someone else pointed out, may have a different reflector. . Yes, like the instructions on this thread - install a jumper so that both bulbs light on high beam only, then the single bulb for low beam. Drive on high beam all the time.
    You're welcome.

    So there ya go driving with hi beams on all tyme Yes in Daytime USA no prob But let it get up to dusk etc then were getting into problematic areas .. No one bothers a bike in USA cuz we have silly dot specs kolo setup crazy scare tactics to get dumb laws on books for revenue etc In the Europe I lived in the Kids drive beeter than seasoned drivers here all the Mods and Nonsense they do to vehicles Here NADa over there will be accompanying paerwork certs etc or vehicle will be removed from road No bartering discussions etc just removed .... KOLO means Key on lights on

    Hi there. Im new owner of SC. All from fabric runs as i want, i notice a few improvements for it but costs time and ca$h. But the only mod i want to do is real dual beaming. Not to do work two bulbs at same time on lo or hi setup. Just replace h7 on the two optics for two h4 and set it up to work both with first filament on lo beam and runs only the second filament on both when turn hi on.

    To start, i questioned about electric power. H4 has 55w and 70w. Normally this bike runs only one bulb of 50w and change it for lo and hi, but only one is working. I readed about the voltage draw with two h7 working doesnt make problems it seems. But do to work two 70w bulbs its 90w more than aprilia mades this bike for. The less important will be the fuse, just put bigger one and full throttle! But, the wiring... I want to believe it will support the watts also... But, will the regulator burns off cause the augment of energy demand?

    After answering that questions and suposes, whats about the handmaking? I make this same conversion on z1000 06 and to match the bulb in the hosing, i mod the plates bulb to make bulb matches into hosing, i can repeat the work. Another handwork will be the wiring. Will be right to use the only wire for each beam and do a derivation to the new bulb? In the case on lo beam is pretty little warming for the stock wire, but for the hi (70w) beam, the stock wiring section will support two 70w bulbs? In that case, the work will be harder i think, change all hi beam wiring for a correct section? I dont know... Thats why i expose this all.

    Probably not a very good idea. H7 and H4 is very different in size, sockets and position of the filaments. You would need very extensive modifications to the sockets to get them to fit physically to start with. And the the two reflectors are differently shaped, one is for low beam and one is for high beam. And the position of the filament/s will be wrong so your light will be all over the place.

    Just forget about this dual headlight thing on the SC, it's just not meant to be. The only thing I find viable is to have the low beam on all the times so that when you switch to high beam the low beam stays on.

    The lamp housing on the Sport City gets enough damage from the stock bulb over time so you are better off leaving well enough alone and at best switching over to LED if your local area allows for it. Even upgrading to H7 SilverStar Osrams can generate enough additional heat to damage the lamp housing without upping the wattage. A replacement lamp housing is not cheap either.

    The Sport City also uses a different system for mounting the bulbs with the bulb holder being part of the wiring harness which adds another layer of complexity to things.

    Rocky is right... just put good strong lamps in it, otherwise you're asking for trouble.
