So I was in cycle gear the other day and came across a LED conversion kit by Speedmetal, They were on sale(as are most things a CG) and claim to have a design which eliminates the scattered light pattern that seems to be a problem for many LED bulbs. I'm a sucker for a sale and have wanted to upgrade the lights on my Stelvio but didn't want HID's because of the warm up time delay when switching from high to low beam on a H4 version so I gave the LED's a shot. Install was a true plug and play with just one plug that goes into the stock light socket. The light pattern is very good on low or high and they are super bright so Im happy with this purchase and just hope they last as long as advertised .
didn't want HID's because of the warm up time delay when switching from high to low beam on a H4 version
There is no such problem. It is one bulb that moves from high to low. It is always on.
Great information. Did you buy two kits (one for each headlight) or do they come in pairs? Is the current draw lower than the stock H4 halogen bulbs or did you install relays ....? Lannis
Yes two kits, price marked as $119. a piece on sale for $59.99 and then an in store discount of another 10% to make it $53.99. No relays just plug into stock headlight sockets that's it. Power draw is 24 watts as opposed to 55 and 60 stock. Im not sure if its a double bulb or only part lights on low but when on low only top part lights then when switching to high the bottom also lights each one reflecting of a different part of the stock lens but very bright and has good cutoff on both beams.
There was a recent post about an LED H4 bulb from ADV Monster that actually has a low beam cutoff:http://wildguzzi.com/forum/index.php?topic=66974.msg1105744#msg1105744
I don't see the low beam cutoff as an issue. You can always adjust the headlight to minimize that. It's the relationship between what they're calling 'low' and 'high' beams and how they make it happen that bothers me.
Only if it's one of the bi-xenon ones Wayne. Some have an HID main and halogen dip (or vice versa, can't remember) and don't have the electromagnetic shifting system.
That depends on the exact mfgr/style of bulb and how they're wired in. I have separate hi beam elements.
The most recent problem for my HID is that it refuses to dip to low beam after being on high. I have to turn the headlight off completely and restart it. With the startup delay it's completely unacceptable in real-time. The mfgr says it's a problem with my wiring. I don't see what could have happened to the wires in the amount of time it took me to do my grocery shopping.
http://www.cyclegear.com/SPEEDMETAL-LED-Conversion-KitIs this how it connects? Looks like an AC plug? I'd assume there'd be a standard H4 style bulb connector.
I don't understand how it works. There's only two prongs on the plug. How does it get hi-beam/ground and low-beam/ground? Lannis
I wondered the same thing, the one pictured on the CG website is for an H7 bulb which is two prong. The H4 version has three prongs.
Thanks, that explains it!!Just ordered a set, I'll report in after I get them in. Probably be after the Maryland rally this weekend.Lannis
Since my Stelvio doesn't use what seems to be the industry standard spring clip to hold stock H4 bulb in place and instead uses a snap ring type of retention system I had to file out a very little bit of the nylon retainer to get the LED light to fit,
I think Wayne O. had to do the same sort of hand-work to the mount to get his HID lights to fit. I'll be ready .....
to be sure, this is an LED bulb replacement for H4 hallogen bulb? Just plug it in & go?I am heading to CG tomorrow. All three of my bikes have H4 bulbs. I put 100wt bulbs on my Bandit, they run hot and the headlight lens is starting to show a dark spot. I've never upgraded the bulbs on the EV or Sport because of fears electric overload & heat. LED sounds ideal.
I don't understand why it hasn't happened before this, LED lights for bikes I mean.
Even though the wattage is less than incandescent, it is a lot for a silicon die. The technology to get the heat conducted out of the single silicon die is recent. I think they are alloying aluminum or some such with the silicon to do it (I think I read that). Note that the large fan is still needed on most of these. Another issue is still there. The die size is huge. Sometimes the die contains multiple LEDs in one. The die is actually larger then the small arc capsule on an HID which is larger that the little filament wire in an incandescent. So light scatter will be worse than HID, and people have complained about those for years. Then there is bulb color. They are going to be very blue. It is hard to get warm light from these, which are usually made by painting a layer of phosphor over a blue or UV LED. The amount of blue contributes to more scatter, more reflected light, and isn't that great for lighting the important things (unless you happen to have blue deer in your woods). :) What color are these LEDs?
