Well I checked, 2 are broken off and the one on the bottom left (looking from the rear) has left a small hole which looks like moisture may foul the sealed bulb cavity. It could be sealed. The 2 OEM lamps/bulbs look good.
Hotboot - thank you. Most appreciative of your looking and your offer. Sorry it took so long to get back to you. I decided to got a different route. Bought some Plastic-Aid that MCN had as their 'Innovation of the Month' a year or so back and glued the three mounting tabs back on my headlight assy. So far so good. Bike should be back together today.
