My middle tail light is out ... swapped bulb and no go ... the one on the left and right are on so I doubt it's a fuse ... unless it has it's own? Any ideas?

The middle bulb is a tail light only. The bulb is a dual element but the wiring is only there for the running light. It is fed with a Green/White wire and a brown wire. The feed comes from the ABS unit itself. The ABS unit also monitors that light as a hold over from the RS model which only had a single dual element bulb in the rear.

On he RS if the bulb (tail light element) is burned out then it thows a fault ( general warning triange is ON; ABS light is OUT) and it would illuminate the stop light element at half power to simulate a tail light. Of course that element is not wired up in the LT. Either the bulb is burned out or the ABS has an issue or a broken wire.

John,

I find all your comments enlightenning.
I too have an issue: when ever I brake hard, the triangle light comes on, the stop light bulb is new. Is it that I may have a problem with the ABS unit?
Thanks
Les

There is no wire going to the middle bulb.
Huh ??? On my 2003, I have more than one wire going to it. I assume one operates the running light, the other the stop light.
Do you mean, you don't have a wire going to it on yours-at all ? Than what trigers it's activity.?
Forgive me....I am really green when it comes to these issues.

It is a dual element bulb. Needs 3 wires going to it. Has 2. I ran a jumper from another
light to activate this one.

I ran a wire to mine but I put a solid state flasher in line with it. Now the middle light flashes when I hit the brakes.

All good advice ... but I changed all fuses one at a time and there is indeed a separate fuse for that light on my bike ... I found a 4 amp fuse blown, when replaced the light now works ... go figure

As a side note ... the middle bulb was the one I used to hook up my tail lights on the DMC wiring harness ... I also use the wiring harness to power lights on my bowling ball rack I made to fit the DMC hitch (very similar to a cooler rack) ... I moved the tail light hook up to one of the outer bulbs so as not to mess with the abs (just incase)

Just an off the shelf one from an auto parts house. I had it lying around and had originally bought it for the Lincoln ut the problem there turned out to be the multifunction switch. I'll see if I can get a part number off it.

Tridon EP-34 Autozone has it Here

Done! That brightened up my brake light a ton!

Hey, thanks for the tip! Think I will try this tool.

Would this work with the luggage rack LED brake light? Installing that same flasher, in line, to make it flash?

It should since it is not load depenent. I haven't tried with LEDs though.

So if I run a wire from the brake light connection to one side of the flasher then from the other side of the flasher to the other element of the center tail light .... it will flash when I hit the brakes?

It has three terminals B, L and E. Run the wire from the other brake light to the "B" terminal, Then run a wire from the "L" terminal to the center bulb. The "E" terminal needs to go to ground ( Brown wire). That is it.

I've had the triangle warning for years. And that middle bulb didn't work - so no light on the license plate. So I ran a jumper from another bulb last summer. Works great now. Still have the "general fault" triangle, but I've been ignoring it this long. . . :D

Okay ... I did this today ... couldn't get brake light to work on the middle light ... if I remove the flasher and connect the wires from terminal B and terminal L together, the brake light works on the middle bulb but doesn't flash obviously ... is it maybe a bad flasher?

I checked the ground to the flasher as good .. so I don't know what to check next ... electrical is not my thing (all my screw drivers have burn marks from accidental welding ... hehehe)

Any help is appreciated

Hope you picked up the ground from a brown wire at one of the sockets and not the frame.
