I see lots of led 1157 replacement bulbs that wii fit my 80 wing. I want a really bright one for my twilight but which ones?

Take a closer look at leds-and the electrical reqierments-you will have to change a few things to to get them going-it isnt as easy at it seems.Regards,Johnyy

For the tail lights? check out superbrightleds.com they have a range of bulbs available. I replaced mine with the brightest they offered. No issues if your changing tail lights. If, however, you decide to also replace the turn signals, you'll need to replace the flasher with the appropriate electronic one. Without the current load, the factory installed flasher isn't going to work properly. Electronic flashers are rather inexpensive and very easy to replace.

Hello !! I have a question, if you change the rear lights only will the front turn signal bulbs create enough resistance or do you still need a flasher? fr1tz

If you change out just the rears, the flasher will not have enough current flow to flash the signals. You need to change the flasher If you go led on either front, rear or both

It depends on the health of your mechanical flasher. It will either not flash, or flash very quickly. You're best off replacing the flasher with an electronic unit.

Could someone enlighten me? Turn signals are used relatively infrequently -- compared to the taillights, headlights and any aftermarket running lights. Does the amperage draw you save with LED turn signal lights make a significant difference?

Thanks.

No. But the instant on/off characteristics of LEDs makes them far more eye-catching, which is always a good thing when it comes to inattentive drivers.

To add to what wingadmin said; in the front they are also running lights - on all the time; therefore you'll see an electrical savings of, maybe, 16W? Something like that...

Thank you both. 16W doesn't seem like much -- just 1.333 amps, right? What is the maximum current draw that you can run on these bikes with, say, an AGM battery rated at 350CCA, before starting to run down the battery, assuming the OEM stator is installed?

You need to look at the capacity of the stator, not the battery. The capacity of the electrical system is limited by the ability of the stator to run the bike and recharge the battery. If you use too much power, you are running beyond the output of the stator, so the extra power is drawn from the battery, drawing it down.

So 16 watts is not much, you're right - but when you consider you only have around 100 watts or so of excess capacity to work with, every little bit counts.

Thanks, GS. I get it now. And that 16W looms a little larger if we've got only 100W or so available.

PAPete - now you see why we are so fired up about LED bulbs...... LOL
