I'm still researching alternative bulbs. Here's what I know so far:

• The factory unit is a bulb in a housing; the housing will need minor modification to allow insertion/removal of just the bulb
• Simply using a higher wattage halogen bulb has been shown to melt the housing
• LEDs will throw a 'light out' code that must be programmed out
