What is this thing?

I recently had heated grips and a PowerHub2 installed on my '12 DL650. The shop that did the project noticed an unexpected wire coming off the battery in the direction of the front of the bike. He couldn't trace the full route without tearing off plastics, so simply told me about it. When he did, he pointed out a device attached to the wire near the battery. See photos below.

When I turn the bike on an LED flashes red, then green, then turns off.

The shop thought it may be something the previous owner installed to brighten the headlights. I haven't been able to get in touch with the PO to ask the question.

Anyone know what it is?






If it's a good day to wash the bike, it's a better day to ride the bike.

Does the Wee have unusually bad speedo calibration?

No.. Pretty much all vehicles (cars and motorbikes) have some amount of inaccuracy in stock form and there are are additional factors that can throw it off even more such as gearing changes, tire size changes & etc... It bothers some people enough to fix it..

I have seen ~10% under floated about depending on tyres and an assortment of other factors. Usually the suggested fix is a "speedo healer". Its a common complaint with a lot of modern vehicles.

All my cars' speedometers are pretty accurate, but my bikes are usually way off. They get worse when you change sprockets and all. I might ride with a GPS for a while to see how bad the speedometer's off, and then use my calibrated eyeballs to monitor my speed.

I did just that, used a GPS to see how far out my speedometer was and once I got a better idea of the difference I took the GPS off. I might chuck the GPS back on at the beginning of the season this year to refresh my memory.

My Wee displays 108km/hr at a true 100km/hr. I believe that manufacturers feel compelled (for legal reasons) to ensure that their speedo's are not pessimistic.
