All things considered; Vibration, Hard Road Thumps, Weather, Corrosion..... I'm surprised at how well the HIDs, with their relatively complex power supply, survive. It's one of those things that works better than it should for the money....... like RainX, OxyClean, Dodge Dart Slant 6 and Volvo 122Ss.
In the Film Business we have used this Technology for the last 15-20 years or so and have had Pretty Good Luck with it. Whenever there is a problem striking the ARC it can usually be attributed to a gassy lamp, or electrode gap that has widened. If the lamp needs multiple starting cycles to fully ignite, a lamp replacement usually cures the problem. Also if you notice the illumination changing color toward Magenta/Purple the lamp is on its way out. Lamps account for 95% of problems.
However, if there is a recent history of Severe Pothole Hits and Submersion in a Monsoon then, of course, check the mechanicals and drainage.
Lamp Life expectancy is a published 2000 hours..... Probably less. More like 1500, SO.......a Motorycycle's Lifetime Average speed overall is, like 35mph by my reckoning even if you/I may think we're a jackrabbit. So that makes an HID Lamp replaceable about every 50,000 miles or so. Pretty good Cost-Benefit-Life Ratio by my accounting. I certainly wouldn't change the Ballast/Igniter/Power Supply.
The Stock headlight was a 50mph illuminator and DANGEROUS, The HID is good for 90mph and worth twice the price. No Squaking about HID cost.
