First off, I want to say that I did do a search but no one seems to be experiencing the same problem I am, so hopefully this isn't a repost.

The front flushmounts were installed by the PO. I'm not sure but I think they are Greggs Customs. They worked perfectly when I got the bike (as both running lights and turn signals). The trouble started about 2 or 3 days ago, or at least that's when I noticed it. The left flushmount doesn't light up at all under any circumstances. The right one lights up very faintly and flashes when signalling right, but it's barely visible. however, the right one sometimes flashes to full brightness when blinking, but it's sporadic and very shortlived.

I removed the molding on each side to gain access to the connectors and check the wires at the lights. While a crude install (twisted together with electrical tape), they are making good connections. I retwisted and retaped them when I was done. I also removed the left fairing and checked all of the fuses, but this was merely a formality since the right one works faintly. All checked good.

I haven't traced it further because quite frankly I don't know what I'm doing. Anyone have any suggestions? Could it be the relay (between the headlights under the gauge cluster, right?) Anything else I should check?

The bike is an '05 CBR600RR with a little over 26,000 miles.

I did some checking online and Greggs Customs instructions are to not wire these up as running lights. Since the PO DID wire them up this way, could that have permanently damaged the lights themselves?

Thanks for any advice, and sorry for the long post. Wanted to include as much detail as I could.

It is unlikely that they would have been damaged by being used as running lights, I would suggest you solder all of the connections cause it sounds like that's where your problem is. Could also be the relay though...

If the aftermarket flushmount indicators are demanding more current than what the relay is designed for, then it is possible that the relay could be fautly. Also, if these lights were being used as running lights in conjunction with turn signals, the PO would have had to install a diode on each side to prevent the current from traveling back through the signal circuit and keeping the signal indicator on the gauge cluster lit. I agree with what Nico said about cutting out the "twisted together mess of tape" and stripping back clean wire and soldering or crimping a new junction. As a benchmark test you could cut the leads to your turn signals, take a piece of 16 gauge wire 4'-5' long, and supply 12 volts from your battery directly to the signal to verify where your problem is. Good luck.

I presume that they were LED flushmounts?

If they have a normal incandescent globe in them it may just be that the globe has gotten a bit old and needs replacing...

Yeah, they're LED. Only 3 of the LEDs on the right signal are lighting up, which is why its so dim. I didn't see any diodes or anything wired in, but my gauge cluster works fine, even with them wired as running lights.

Sounds like they could just be dead then... are you sure that they are not cheap Chinese knock offs?

They were installed by the PO, and I don't have receipts or anything, so I really don't know what they are. The Greggs Customs are the only ones I've found that look similar to the ones on the bike. I just wanted to try to figure out if there was another problem before I went and dropped $100 on Protons.
