As with most XS's, for every action, there is a equal and opposite reaction..
Today, in my quest to reduce some of the current draw on my battery, I purchased a new Led Brake/Tail Light bulb,, "direct replacement for 1157" ... cost 16 bucks. ( my bike is 1975 XS )
( streetglow.com part # SGL1157WH )
OK, so now my brake dash lamp,, the little red "Stop Lamp",, is now blinking,, fast but regular ( like the blinkers but not)...
When applying the brakes, the dash light comes on, and is steady red, as it ought to be.
My new brake light and tail light works, and I am sure there is less draw of current,, but who would think the technology in 1975 would tell the dash light to blink...
If I put the old 1157 back in, of course the blinking goes away.
*
Choices:
Put the old bulb back in.
Take out the blinking stop lamp bulb ?
You may have a better solution ??
or other sound advice ?
Thanks to all ...
Blessings to you

it looks like it needs a bit of resistance on the brake light, you can try to put a ceramic resistor parallel to brake light as for how big(OHMS) I'm going to check mine in the morning and try to give you a #, i have a bin with some resistors. it's flashing because it thinks the bulb is burnt out

Thanks Speez;
then, if i put the resistor in line, (which i assume draws a little current ) is it not just as beneficial, to stick the original bulb back in ?
Right now, i have some black tape, over the red flashing light. (as it drives you crazy )

your correct on the load being there but, you only putting (resistor) it on the brake side of the bulb as your tail light you will benefit on saving some current as that stays on all the time

OK! got the 411! the first resistor i grabbed and it stoped the flashing light 1K so i didn't bother to check others and it was a 1/4W it doesn't need a ceramic resistor,i put those on led turn signals so they flash normally, but you don't need that as you are putting a small wattage to fool the bulb checker so you can use a 1/4 or 1/2 watt resistor 1K, BUT! i don,t have led tail light so test everything, i just removed the plug from under my seat light started to flash put resistor on to ground and puff! it stoped to flash
p.s. you will bypassing your bulb checker,but with a led brake light you should be safe,just check it once in awhile

i just thought of something, if you are going to put resistor try this test , jam brake leaver so it stays on and then put in parallel the resistor and see if the brake light dimes if so you might need a hi'r resistance

Thanks Speez..
when i find a little time, i will go to work on this issue.

Using an led bulb helps lower the current draw. To put a resister in to increase the current draw to get the brake warning light to not flash is kinda self defeating.
Just remove the light checker. That's what senses the blown bulb and lights the red dash light.
Or just put the regular bulb back in.
I added LED's to the tail/brake light and turnsignals. I also rewired the bike to get rid of all the bull, the only thing I kept was the safety relay, that protects the starter gears.
I don't need a light to tell me the brake light is out or if the rear brake pads need changing.

XS thanks,,
forget my question on the other post.
I did remove my "rear brake shoe indicator light" ( how innovating ).
I hack-sawed the tab off the backing plate and took a while to file that nub down...
... but yes, I will keep my shocks, thanks.

by adding the resistor to "only" to the brake side of the bulb your running light benefits on saving current as that side of bulb doesn't see the resistor ..think at what % the brake light stays on? compare that to % of the running light?

for 1157 brake light, the two contacts connect to 2 positive terminals, the metal cap connect to - negative tearminal. one positive is for bright lighting as tail light signals, one positve is for weak lighting as stop light, did you install in a correct way?

yes dingjuled and welcome aboard...
it (the LED light) works and perform, perfect, as it should.
it is just so low of resistance, the dash light, does not sense the bulb in in there.
all is good.

have you ever taken the light bulbs apart from your bike? And switch on 12VDC current, and see whether it is still blinking, if so, I am sure that your LED bulbs doesn't have a resistor, I work for a car LED light factory,¡¡a resistor can protect your LED working without over current.

I'm with Leo - At first, I just pulled the bulb in the dash - and when I rewired the bike, I removed the light checker totally. Just check your lights before you ride - even LED's don't like all the vibration from this bike..... I've had a few of them get shaken apart.
