LEDs themselves (by their vary nature) are polarity sensitive. However, not all LED modules are polarity sensitive, as this depends upon the driving circuit built into the LED module.
For example, in my own LED conversions, I've had very good luck with the 6-LED (194 replacement) "WLED-xHP6" (where x varies with module light color). They run around $5/each from superbrightleds.com, and in my experience are noticeably brighter than stock 194 bulbs (like all LED conversions, get the modules that match the light color to the car LENs color you are putting them behind). And (while I can't find this detail on their web site) I seem to remember (that when I last installed them in a family car) they worked BOTH WAYS in the light sockets (which would imply that their driving circuit compensates for reverse polarity before feeding the power to the LEDs).
Of course, YMMV, but they may be "worth a shot". If nothing else, you could get one or two of them, and give them a try (as they aren't very expensive to purchase). In fact, two of these modules (either amber, or red, depending upon the color of your side-markers) + their cheapest shipping option, will only set you back around $15 total. So if they don't work as you like, you still haven't lost much.
FWIW: My Honda CRX came stock with it's front amber side-markers doubling as secondary turn signals. And yes, I did eventually replace those lights with the 6-LED "WLED-AHP6" modules (from superbrightleds.com) in both front amber side-markers. And IMHO those "side markers" are now bright enough that they now make more noticeable front "turn signals", during the brighter part of the day, than the actual (brighter, but not as close to eye level) real "turn signal" lights (in the front). So at least on my car, they work very well. But, of course, YMMV.
