Givi E92 Light Kit Fail - Solved!

I installed the Givi E92 light kit on my Givi E460 top case last year. It worked for a month or so before it started to work intermittently, then stopped working altogether. I troubleshooted the wiring last year, which was time consuming, to no avail and gave up until this year.

Tonight I went out to try to solve this mystery again, and out of frustration I hit the top of the box, and wouldn't y'a know it the LEDs flicker on and off...

So I know this isn't a wiring issue anymore, so I take the kit apart, remove the LED strip and inspect. I notice one of the led bulbs is a tiny bit loose in its' soldering. I attach the LED light strip to a 12v battery and am able to reproduce the light strip going on and off depending on the position of that one loose LED bulb.

A little soldering, and 20 minutes to put it all back together again and I have a fully functioning top case brake light.

Posting this in case someone runs into a similar symptom, maybe try a little tap of the top box a few times before diving into all the wiring.

... or better yet, test the LED light strip, and gently test the soldering on all the bulbs, before installing

Glad you brought this up. I'm revisiting adding lights to the red lens on my K48 top case.

I looked at doing that years ago, but at the time I could not find a US source for the official kit (V90).

So your E92 kit uses LEDs? Revzilla describes the kit as using incandescent bulbs (https://www.revzilla.com/motorcycle/...e460-top-cases), so maybe there are two or more versions.

Did you have to drill a hole in your case to run the wires? Are you satisfied with the brightness? Some people have been disappointed with the (lack of) brightness in the official Givi kits, from what I've been reading.

I'm looking at making my own lighting kit for my K48, using SMD strips. There should be room for at least two strips. I just have to think about where to put the wires, and how to hook up the whole works.

Not sure if I'm entertaining anyone but myself at this point, but I'm working toward rolling my own stoplight kit for my K48 case.

The "proper" factory kit being unobtainium, and Kappa having not answered my query vis-a-vis V105 compatibility, I'm sourcing my own components.

Soldering seems to me a weak point. Given the vibration-prone environment I prefer to crimp when possible. This is an area I think I can improve on the "official" lighting kit.

The lighting area in my K49 topcase has holes for four 5mm/0.2" LEDs so the plan is to wire four white LEDs in parallel. I have a healthy supply of marine-grade 16 gage wire, crimping materials, and automotive-grade, weatherproof electrical connectors. Overkill, probably, but better overengineered than underbuilt.

I thought about turning the "stop light" into a running light, but I feel the top case lens will have the most impact lighting up all at once, only when I apply brakes. Also, I'm not sure the lens is designed for an always-on duty cycle. While LEDs don't throw off that much heat, I don't want to find out I miscalculated by melting my lens.

Illumination will be further enhanced by means of small triangles of white trailer tape lining the spaces where the LEDs go. It's pretty bright just with reflected light, even through the red lens material, and should be quite brilliant with lit LEDs.

FYI, my "fix" failed not long after. I give up lol.

Going to have to be satisfied with a standard brake light.

It uses a 4 LED strip. When it worked it was bright and I was very happy with it.

If I can find an LED strip that can fit in the same space I might consider giving it another try since it's already wired.

Thanks for the update, and sorry about your luck! I'm guessing it's another solder joint failure? LEDs themselves are pretty darned reliable today, although it's not impossible that one failed. They are most likely wired in series, which means if one goes out, they all do.

I think some vendors need to update their product description re: Givi lighting kits using LEDs, not incandescent bulbs.

If it's not too much trouble, could you please post a photo of the LED strip from the lighting kit? I'd much prefer to borrow Givi's design vs. reinvent the wheel myself.

An SMD LED strip would of course be the easiest fix. I might go there myself, if making my own setup proves infeasible. When you roll your own LED array you have to consider all sorts of things like current-limiting resistor value, providing a constant-current power source (usually using some kind of IC), dissipating the heat from that IC, it gets complicated!

This is the closest thing I can find:

https://www.amazon.com/Black-White-W.../dp/B01D4Y7Z4M

This is far more SMD strip than either of us needs (5 meters!) but one end comes pre-wired, it's already set up for 12V power, you can cut to desired length in 5 cm increments, and it's pretty cheap. So, cut off the first 3 or so segments, wire that in, and use 3M trim tape or similar to hold in place.

What do you know, this morning I got a reply from the Kappa folks in Italy.

The meat of it is an educated "maybe":

Quote:
...the item is not identical but it could be compatible.
So there's that.

You could also look at a kit from Admore lighting. They show a kit for the E360/E460 on their site under the top mount section. Not cheap but they have a good reputation. I myself have not used this kit, but I have used their other products and been very happy. Admorelighting.com
