'performance tuning' your crappy b15s '1156' headlight bulb

so this LED stuff seems like it changes every time i turn around but i noticed there are some folks on amazon selling more powerful 'b15s' socket (same socket as most moped headlights- same as 1156 bulb) LEDs.

Anybody try these? Or something like it? Can't be worse than the stock dim-ass bulb right?

and yeah before you ask i'll be using it on a regulated 12v DC system blah blah blah .

Re: 'performance tuning' your crappy b15s '1156' headlight bulb

What about these for us 6V DimLits?

Re: 'performance tuning' your crappy b15s '1156' headlight bulb

Don - you can get the fathead headlight BAX15d bulbs from Mopedland in UK

BAX15D 6V×15W/15W beam/dip. Large head, 15mm bayonet. £2 each.

BAX15D 6V×18W/18W beam/dip. Large head, 15mm bayonet. £2 each.

BAX15D 6V×20W/20W beam/dip. Large head, 15mm bayonet. £3 each.

BAX15D 6V×25W/25W beam/dip. Large head, 15mm bayonet. £3 each.

These are dual filament but the side pins are aligned to each other, not one higher than the other, but one is longer than the other. Folks with Euro sped headlights will be happy because it is something with the bike (having troubles replacing just a bulb)

Also Danny has the single tail light in various flavours and the double filament - both in 6v...

Re: 'performance tuning' your crappy b15s '1156' headlight bulb

Thanks,Rebel! I'll take a look!

Re: 'performance tuning' your crappy b15s '1156' headlight bulb

Yeah I grabbed a couple similar to what you listed for taillight on my dt250 yammie. We'll see how they work out, in the past I've had issues with the fact that the ac systems in mopeds go way over 6v to something like 30v at full speed.

Re: 'performance tuning' your crappy b15s '1156' headlight bulb

Forget all this and look at Larsen lighting. He makes led tractor headlights that fit exactly and entire units. Night and.day in form and function. It's been mentioned here before. Once u try them u will toss all other led headlight contraptions.

Re: 'performance tuning' your crappy b15s '1156' headlight bulb

yeah i was looking for something that would be a drop-in bulb replacement but for 30 bucks its tough to go wrong with the larsen. i noticed they are selling a 'high output' version now that is a bit more wattage than the regular one.

like i said this technology changes fast so i'm always into trying new stuff and seeing whats out there.

Re: 'performance tuning' your crappy b15s '1156' headlight bulb

Try Larsen u will never look elsewhere. They Excel

Re: 'performance tuning' your crappy b15s '1156' headlight bulb

I've used those LED lights, the cheap ones are cheap, they ledsare glued in with tiny little solder wires to the bulb's base and I definitely broke em easily. Still, they are bright, though flood more than beam. I've used em in my car too, they don't like getting wet but work otherwise.

I also put one in a really quick bike direct off the lighting and no regulator and they lasted months before blowing. so I expect theys be legit

Re: 'performance tuning' your crappy b15s '1156' headlight bulb

yeah i've had the same thing with the cheapy ones, i have one in one of my bikes that got so hot the solder melted... i soldered it back together and hosed a bunch of epoxy all over it and it has lasted years with no reg no rec.

fuckit whatever i'm gonna buy them, who knows maybe they'll work in unregulated 6v AC system too. worst case i can put some cosmically bright brake lights in my subaroo

Re: 'performance tuning' your crappy b15s '1156' headlight bulb

I'm experimenting with these. Looks the same as one on Larson's site. So far it looks promising. $20 for two.

♣Slew Foot♣ /

I've rigged up an H3 halogen car bulb to fit inside a stock Tomas Square headlight and it can handle up to 75 Watts but we'll run at 40 problem is he gets really hot so I had to switch back until I find a better bucket to modify

Do they come out of the housing or do you have to mount them with the single threaded stud?

Re: 'performance tuning' your crappy b15s '1156' headlight bulb

They include the mounting bracket and hardware. I was hoping I could remove it from the housing but no go. No bolts, it's glued. Tried a heat gun and quit when the reflectors started to discolor. I trimmed its eyebrow and the mounting tab. Then epoxy to chrome CEV housing. Looks good and can't be beat for $10. Brighter than stock and low wattage on the 6 volt system with rectifier/regulator.

Re: 'performance tuning' your crappy b15s '1156' headlight bulb

got that crazy bulb in last night, popped it in just to check it out.... revved up for a few minutes and let out the magic smoke. super bright, hurt my eyes.

i'm redoing the electronics on my maxi right now so i have enough power to run a stupid sound system but i think its gonna be great with 12v regulated.

Re: 'performance tuning' your crappy b15s '1156' headlight bulb

For my hobbits I'm going to cut the rim of the Stanley unit away from the reflector metal and glue it to a Larsen light. Then mount like a any Hobbit light. Frank's light is exactly what's on my cev type bucket. Instead of the weird little springie clips e6000 glue.

I’m running these bulbs in my ciao, I milled down the outside of the aluminum housing the led is mounted in and fit it in the stock headlight bezel using the headlight clips. I also had to take a small amount out of the headlight ring so the clear lense could poke through. (edited)

I bet you get bright flashed . ;)

Lolz......every time he rides.

Seriously though, I need to try my hand with something like this.

I'm thinking regulate current or voltage down a bit for "low beam" then full power for "high beam" when I get "bright flashed". (edited)

Nice Joe. I just did it the easy way. Hack saw, grinder, and cutoff wheel mounted in the drill press to trim the eyebrow. Going with full wave regulated DC for headlight and taillight. Just a 4 diode rectifier for the stop circuit.

Did you do a write up on that^ ? If so , please post a link .

If not , is it still feasible to do a write up , maybe even with pics ?

I know I've seen , at least, bits and pieces of that procedure .

Re: 'performance tuning' your crappy b15s '1156' headlight bulb

My $10 light looks good to me. GY6 regulator, floated the lighting coil ground. Kept the AC powered brake light. Added a diode just for insurance.

20190717_213230.jpg

Re: 'performance tuning' your crappy b15s '1156' headlight bulb

what gy6 regulator are you using?

i've been messing around with these guys for years and just finally think i have them totally figured out. they aren't complicated but they are weird enough to be a little confusing if you don't get it.

gy6 regulator

you basically need a double tapped coil like the treats 'puch 12v coil' with the yellow and green leads.

for full wave you need the one with the side fins, i bought one of them to mess with it but i haven't quite gotten it scienced out all the way just yet. i floated the ground on my TSM with MBK CDI and i'm going to be tearing into that project pretty soon.

Re: 'performance tuning' your crappy b15s '1156' headlight bulb

Full wave gy6 reg/rec

this is the one that does the full wave with the side fins- i'll be using it on my TSM we shall see how that goes. haven't used one before.

Re: 'performance tuning' your crappy b15s '1156' headlight bulb

These are good. It's a little larger than the others but I liked the leads for Bullitt connectors. The stock V1 lighting coil seems just good enough. For $30 or so I have front and rear LED lights. I'll add another for the indicator light and Speedo. This Roadmaster was quite decrepit. I'll post some before and after pictures in the general section sometime.

I made this bracket for it.

Re: 'performance tuning' your crappy b15s '1156' headlight bulb

This did inspire me to upgrade my motorcycle lights, I used these same ones. fucker! theyre bright and easy. but that's with a battery.

whatabout just adding a battery?

Re: 'performance tuning' your crappy b15s '1156' headlight bulb

it's funny that those full waves have side fins, like shouldn't full wave dump less to heat?

also can you just run em off a single input? If not, why not? or split a single input to both "in" tabs parallel?
