Anyone know a good source for a reverse polarity 1157 LED bulb or...
A replacement LED tail light assembly that is compatible with the 2005 Outlander exquisite wiring?

Incandescent?

Does it really matter??????

Are you making a funny?

LED may matter - test it and flip the pins if necessary. Extraction tools are easy to come by...... I think

Evidently you have never dealt with the unique wiring associated with a 2005 Outlander tail/brake light.

The base of the light socket, which is normally ground is now 12 volt hot. And the two pin contacts for the filaments are now grounds.

One positive, two grounds.

Flipping around any wiring, contacts or bulb is not an option.

A standard 1157 LED bulb will not work.

Yeah...this happened with me and my 2007. Total mind bender.

Tried LED, gave up in frustration, immediately went back to incandescent.

Thanks for the history lesson.

But curious...WTF? Why would they do it this way? Must have been a reason.

Evidently Can Am owners are not alone.
Taken from another ATV forum...

"Polaris uses unconventional positive ground system on most tail/brake light wiring. Read has to do with wiring lasts longer due to galvanic corrosion of negative ground?"

Sorry about the mis-lead

No need...
We are all here to learn and share our experiences and advice good or bad. Then when we discover we/I/you were wrong, we man up as you did, admit our mistake and move on. No harm... No foul.

BTW... What you did say about reversing the LED bulb or it's leads is true in normal wiring situations.

Well - LED lamps are diodes hence the "light emitting DIODE. Current can only flow one way through these things, correct polarity is essential to their operation.

@Kusa may be able to elaborate more.

I seem to recall my Popps train garden with all little street lights and such. He would install resistors on the short leg of the LED lamp to change their color. This was years ago, early 90s I believe.

Incandescent lamps don't really care about polarity as both legs are equal.



I never would have thought a brake peddle or leaver would reverse polarity.....GEEZ. A relay is the only way.

Cheers-
