I need some help with a 6 V tail light bulb. Right now I am using a 1154 which is a 6 V dual filament. But the glass itself is too large. I need a smaller glass. Anybody? Have any books as I do not have one. As you Can see the glass itself Sticks out too far. I know they make short ones for the 1157 12 V bulbs but I can't find a part number for a 6 V one.
I think this is where you need to look... Amazon.com : motorcycle turn signal light bulbs You can still get small bulb incandescent lamps for these but they were famous for short life as the smaller glass couldn't dissipate the heat generated and they would burn out fairly quickly (most were packaged with 4 or more recognizing this). All I could find are single filament lamps, not dual, so they're either turn-only or running light only. I'll note these were also known for melting plastic lenses. There are however multiple listings for LED-based lamps, some with dual function. This will probably be your best choice.
The problem is the customer put in 6 V LED bulbs, but the flasher Wont-work with it. But if I put in 6 V bulbs, everything works fine. So I either need to find 6 V, short bulbs Or an LED 6 V flasher, which is a week away or non-existent.
Yeah, I missed the 6V... Those lamps were always a small niche market item and semi-hard to find. I didn't see any 6V versions currently. What will probably be easiest to do is install a resistor in series on the load side of the flasher to emulate the load. I'd talk to a LED lamp supplier to see if they know a solution. I know that for a 12V led, using a 6 Ohm resistor will correct this (it needs to be rated for at least 50 watts) to 'fool' the flasher into seeing the correct incandescent load. Do you know the wattage on the turn filament?
If you really get stuck, you can remove the glass, etc , from the bulb and solder in a 6v hi-intensity LED. You will need a 270 or 330 ohm series resistor for a 20mA LED. You may even have enough room to install a complete (but smaller) 6 V LED bulb into the old base, solder some tails onto it, and connect up to the old base, then epoxy it all together. To get the whole thing to flash, you need a solid state (electronic) flasher can. These do not rely on current draw to operate.
Get a pair of B-31 Guide backup lights. Same style, next bigger size. Plenty of room once you rework the socket for dual element. If you need them for rear, '40 Plymouth stoplight lenses fit.
Thanks all. Can't find a bulb to fit in the customer supplied housings So I ordered a six volt led flasher So it can run the six volt led bulbs it came with
You could also use a voltage reducer in series with your bulb(s) for a few dollars more. Amazon has a few that you could use. Or, if you have a couple of 10,000 ohm resistors (5-10 watt rating) hanging around you could wire them in series and tap the junction between them for a 6v output.
