Yes 50 volts is about right and it must be as close electrically/physically to the hid light power in (12 volt) leads as possible to improve the application. Bigger may assist but not over 300 microfarads, I suggest ( per light module).

As the battery ages it gains internal resistance or lossy internal structure. The cap stores charge and acts to keep the power system more stable, ie less noisy especially for lights that are basically high voltage switching supplies that backfeed lots of hash - static - or noise depending on your background.

Cheers, Woody
