Headlight relay not needed on Glee?

The headlights on my 2012 shut off when the starter button is pushed, that being the case why would a relay be needed to save the starter switch from frying?

The 2012 works the same as models from 2005 on up. The headlights shut off so the starter motor gets all available power.

It's the set of contacts that provide power to the headlight that are protected by the relays. Anytime the bike is on, other than starting, those contacts are in use. That's what you're protecting.

So I'm correct in that a relay would be of no use in protecting the starter switch from overloading with current feeding the lights?

Once again, Nothing changed. The Glee needs relays to keep the headlight load on the starter switch contacts from making the contacts eventually fail as well as other connectors. The starter switch headlight cutout has been causing problems since 2005 and 2012 is no different. Get relays if you want years of trouble free operation.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s

The purpose of the headlight relays has nothing to do with the starter switch.

The starter switch and headlight switch are two different sets of contacts, two different circuits. The headlight relays protect the headlight contacts and all else in the headlight circuit.

I'd guess he was talking about the normally closed headlight contacts in the starter switch and not understanding why they need relay protection.

A set of Eastern Beaver headlight relays is on the next up list, along with a PC-8 and some other power goodies.

Two issues, first is wear and tear on the contacts, second is the 'only just adequate' size of the wiring.

I put the relay in quite laht on my K6 (50,000k's or so), lights went from yellow to white without changing the bulbs

That's exactly why you need the relay... Too much current (like the last gen wees) is running through the starter button switch... eventually burning up the contacts...
