Hello all,

Todays question is about LED lighting for my 2015, K1300S. Last fall I installed the Cyclopes Low Beam and Parking lamp. All went well without any Lamp Failure indicators. This winter I installed LEDs in the turn signals and again no Lamp Failure indicators lit up. Recently I installed the High Beam bulbs (2) and the Lamp Failure indicator came on when I used the turn signal and would flash when the turn signal flashed and then would stay on steady. Took the bike for a ride and would run thru the start/shut down sequence a few times but the indicator stayed on.

This morning I took out the (4) turn signal bulbs and replaced them with the OEM bulbs and now it seems fine. I would like to use the LEDs in the turn signals to make the bike more noticeable. My thinking is I'm significantly under the Amp draw for the lighting circuit and that is causing the Lamp Failure indicator to come on? Do I need different turn signal bulbs (ones that draw more)? I bought them from suggested seller from Amazon that I read about from fellows here. $40.00 for the (4) of them pretty much. They seem like they are well made and they fit perfectly and are significantly brighter.

Any suggestions ?

Thank you

After a few more email exchanges with Cyclops I’m going to try a resistor on one high beam bulb to add some load. I’ll report back.

I'm running MZS LED H7 bulbs (from Amazon) on my 2008 K1200S in both high beam and low beam locations. No LAMPF faults and they're super bright. They fit neatly inside the headlight housing with out issues. Frankly, I think Cyclops is outdated and expensive for what you're getting. The MZS bulbs were about $35 for two. I bought two sets for $70 and have a spare if I need it.

Hornig makes replacement LED panels for the rear turn signals that will not cause a LAMP fault, but I have yet to find plug in bulbs for the front turn signals that will do the same.

These work in the front, bright as hell, no need for resistors.

To the threadstarter, get a hold of 4pcs 1W 68ohm resistors, connect one to each turnsignal and you are good. Remember connect the across the wires, paralell, not in series. Keep them from touching plastic if you intend to keep the turnsigals switched on for more than a few minutes, they get hot.
