I have a couple of lights I've used as 194 substitutes in the past, these are my top 3. The 14 has a very small bulb cavity, so you need to be sure that the bulb's circuitry doesn't extend too far out, otherwise the bulb bracket won't screw back into the housing and you're boned. Here they are...
First up: these ones are slick, they're bright for their size, and they're available in multiple colors. I have several of these in my 2007 Impala, and they have performed admirably for the last 2 years they've been in the headlight side marker positions (tight clearance issues here too). The 5050 LED chips are killer because on each chip there are actually three individual diodes, as opposed to the 3528 LED chips, which only have one diode per chip.

Next, these are essentially the same SMD LED as the above, only instead of five 5050 LED chips, there's only one. I used these for the city lights on my 14 until I replaced them with the next model. Not obnoxiously bright, but performed very well, and available in several colors.

These are what I currently have as marker lights on my 14 (for about 8 months now, with no problems). They're very bright, and have the added bonus of strobing. I like flashy and eye-catching, and so long as the ones you get aren't blue or red, the heat shouldn't hassle you about them. To turn on or off the strobe function, simply cycle the bike power. These lights are STUPID bright for 194s, and the strobe feature is a real eye-catcher. Be advised: if you don't like the strobe function, these can be a hassle.

I've bought a lot of LED bulbs through these guys over the years with only one problem (bad design on one bulb type, and they made it right). I hope this helps!
