LED rear lights questions

Hey all,

I have been trying to install rear turn signals and running/brake lights LED's for some time now. I have two problems now. Any help is greatly appreciated:

1. I have installed a 6 Ohm, 50 Watt resistors in parallel for the turn signals and made sure the connectivity is there, but the LED lights still do not blink. I have tested the bulbs on a 12V source and they light up with no problems that way.

2. Anyone can suggest a good source of the running/brake LEDs. I bought two sets of lights separately using different part numbers both of the times from Ebay and in both cases the bulbs have the plastic base vs the glass base the regular bulb has and it does not fit properly into the socket.

Thank you.
Cheers,
Mad

Do the normal turn signal bulbs flash? Will the LEDs hyper flash if the resistor is not in the circuit?

The normal bulbs are 1156 and single contact bulbs, 1157 bulbs are dual contact base bulbs and will not fit in the 1156 base because the pin configuration is different.

If the LEDs will hyper flash but wont flash with the resistor perhaps the resistor is too much for the flasher in the Combination Meter board.

I am not sure if those bulbs are 1156. The 1156's have 180 degree contact placement where on the SWing those are at 150 degrees. Anyway. When I install the OEM bulb with the resistor in place it flashes normally. The LED does not flash at all, with or without the resistor.

Thank you.

Not quite sure what you mean by 180° vs 150° contacts but this picture might explain the pin and contact placement of 1156 vs 1157.

Worst case scenario; you'll need to bypass the flasher relay in the combination meter board. Here is a link to a "how-to" from the Singapore Silverwing forum. Sure it's for an Asian FJS 400 model, but the wire color codes and procedure should be the same.

If the link doesn't take you directly to the flasher relay post it is post #226.

Hope this helps

Tim,

Thank you so much. This is exactly what I was looking for. I ordered a solid state flasher and hope it will work for me.

Never mind

Hey Mad,

This is what I'm using for my brake/tail lights...

They are bright enough, where all the other LED replacement bulbs I've tried have not been.
Also, they work fine with my brake light modulator.

Are you replacing the amber turn bulbs with LED's or adding additional lighting?
I've never been able to find an amber LED that has enough output for a turn signal, and in the past went the other way...high output halogen!

If you find an amber LED that's as bright as the stock bulb please share the link!

My additional LED's are just paralleled to the rear harness, no difference in rate of flash.

Some time ago I replaced the rear turn signal bulb sockets to a double filament socket. This allowed me to be more visible from the rear.The sockets
are the bayonet(twist and turn) and are quite common. They come with short pig tales to wire in. They can be purchased at O'Reilly's or most any auto parts store. The best one to use have metal fingers to hold them in the housing. I then spliced in a lead from the tail lite.This gives me a extra tail lite.
The double filament bulb is a 1157. At first the only bulb I could find was more amber than red. After a year or so they came out with a LED that
was a true red and much brighter.The LED bulb use less amps and blink much faster,this I like. I did not have to make any adjustments to the brake or running (diode-resister)  lite circuit in any way. I have noticed a distinct difference in the way the cages back off from my derriere after this modification.        Howard

My question=why? Standard stuff works fine----meets regs. If worried about being hit from behind, much better to work on riding skills.....how about High Vis jacket/white helmet.....and proper positioning in traffic.

Curiously those Philips 7443 LEDs don't indicate that they are applicable for turn signals or turn signal / running lights.

I suspect that the reason that your LEDs don't alter the rate of flash is because the OEM 1156 amber bulbs are supplying the required circuit load.

Tim

The 7443LED's are in the brake/tail position, the turn LED's are a Kisan Vectra license plate frame and a pair of side reflectors with internal LED's.
These are wired to the stock turn bulbs, which is why I have no issues with rapid flash.
If someone ever produces amber LED's that have an output greater then the stock 1156/1157 I will switch over to all LED.

I'm thinking of adding a pair of the LED driving lights to the rear like the ones I have up front, but will add an amber beehive lens to them to make an ultra powerful turn signal!
I'm going to mount them under the rear box, facing forward angled about 45 degrees.

The correct part number for red LED double filament bulbs from Auto Zone
is 301734. When I made the rear turn signal to a ruining lite and turn signal combination the only socket available was the bayonet type.Although of a older design they are less problematic to loose connections. As stated I am pleased with the performance of the LED's. When I can coral one of my 12 year old  grandsons I will show the operation on site. Howard

The link I posted is for the latest generation Phillips bulb, not the old style SMD5050 types that they sell at Autozone, Advance, Walmart and others.

This new bulb has just come out this year, It's red and bright as a stock incandescent 7443.

I've done the LED "Full Monty" on two other bikes and was not able to match the output of the stock tail light bulbs until now.

Since we have so many bikes/cars with good LED's from the OEM's we know it can be done, it's just waiting for the "good" emitters to "filter down" to the replacement bulb market.

Mad,

How did you get on with your LED tail light problem?
