    Hello,

    anybody out there mount and use the Piaa 55w aux. driving lights on their LC4 ? I'm interested if this will work with the charging / electical system without problems or if this is too much drain. I've got a old pair off a previous bike and wanted some real world opinions before I mount/ wire up.

    tks, bryan

    Thanks for the ideas and responces ... my application is for a
    2004 KTM SMC 625 ..didn't know all those lc4's had different charging systems.

    You only have 200W maximum to play with. Throwing 110W at two driving lights will get you close to battery drain. Why not look into HID?

    That is good advice, and there are reasonably priced options too.

    Would love some links or info. Haven't seen much specifically relating to the LC4 Non-Adventure...

    I've run one 55W aux light on mine with no problems. I made a bracket out of a bit of alu angle to attach it to the handguard mount.

    Cheers

    No this is a good point Chrissy-poo - differences between the E and ADV. I don't recall any statements on the E's charging output and standard load.

    Thanks Clintnz! I've been watching the Lord of the Rings movies again (bedridden with the flu) and lusting over your countryside... :tb

    Come to look, the original poster didn't say which model LC4...

    E should be the same, save the minor difference in the headlamp... Herr Meatsheisse :deal

    The headlamps are the biggest piggy-poo(s) in the ADV system, so "minor" may not be an appropriate qualifier :fitz and clintnz is a very reliable source of poop.

    That's not right either... how about Fleischkopf? Hey, wait a minute, some bugger's already got that handle. How about Herr Fleischstock?

    I doubt there are any differences. I know I've run 60W high beam + 55W aux light + 35W heated grips for long periods with no probs.

    Good aye! I might have to watch them again soon too & get some inspiration for the next Sth Is trip. Get well soon :D

    Cheers

    the lc4 e has the same charging output as all other "640" lc4 engines. chris is right... 110w is bordering on the edge.

    you may be ok. you probably will not. if it's an adv bike you've aready got your 2 oem lamps, then you wan to double them with a couple hundred watts max?

    hid is by far the best option. trailtech are nice as are many of the hid conversion kits available online (ebay has hundreds). i'd try an hid in the main lamp first, then add more if need be.

    thanks for the confirmation on the charging system output loaded.

    Yep, so it seems there is little difference between the H4 and H1 bulb amperage draws (E vs. ADV). Yes clintnz says he has run a second 55W light, but perhaps that is no different than the somewhat popular HI/LOW or both lights on at once mod on the ADV, which seems to work for those who use it, properly.

    ChrisC started this... :fitz

    There's not much difference in amperage in the stock setups between the ADV & E but the different lamps (single H4 vs dual H1) really change the approach for HID conversions or using both hi & lo at once.

    You'll probably destroy the lamp and housing with heat in a E with the H4 re-wiring to run both at once because both filaments are in in a single bulb/housing that's not made for that kind of heat.

    Converting a H4 system to HID is tricky because the H4 bulb has two filaments, one for hi and one for low. HID lamps cannot fit two in the same space like the H4 so they use various kinds of moving bulbs, shades, or HID+halogen units. None seem to work that great and there is no way to use both hi & lo at the same time.

    That leaves us with the E to get real creative when we want more light.

    There actually is H4 HID conversion sets with dual chamber HID bulbs.

    Can someone post some links?

    I'm looking to replace the weak OEM headlight in my 625 SMC. Two guys I rode with recently had HID H4 conversions on their XR 650 Hondas. They REALLY liked them, and it was apparent to me how much brighter they were than mine. They said something about getting them on eBay for about $100.

    I'm not very good with electrical work, so any help here would be MUCH appreciated.

    Thanks,
    -Banning.
