Replacement bulb problem

You can try using a heavy wire (think coat hanger) with some tape on the end or one of those grabber tools with the plunger activated prongs to try and snag it.

Not sure about the condensation though. You must live in a really humid area, or it's been raining since the bulb fell in, leaving a n open hole for the humid air to get in. Normally, you would need some kind of dehumidifier or dessicant to dry out the air in the headlamp. Perhaps you can try to make some kind of small adapter to get a vacuum into the headlamp and draw out the moist air? They sell some adapter/attachments for use on computers and keyboards that are pretty small, that might help.

 

Not sure about the Prius side marker bulbs, but to access the side marker bulb on the Camry the front bumper cover needs to be removed, or at least loosened and tipped away and the headlights need to be pulled out. SMH.

 

I have a 2012 Prius and reading in the manual, minimal condensation is normal. However, if you start seeing water accumulating then you have a problem.

Sucks about the bulb. I dropped a bulb in the engine compartment of my Ford Focus (last ford I will ever own) many years ago. I could not find it for the life of me. So I went and installed another one and forgot about it. About a week later I drove down a rough road and started to notice some loud squealing and a burning smell. I pulled over and had the car towed. Darn bulb had dislodged from wherever it was and jammed a pully/flywheel. The bulb had shattered but the wire and plastic is what did it in. Be glad it's stuck in the light housing.

 

Condensation, try a hair drier blowing warm air into the housing.
Just like when you want the bathroom mirror to be clear of steam/moisture.

I also saw the manual that said condensation was normal. If you ask me that is an out for Toyota, CYA.

My dealer said the same thing, normal. So I took matters into my own hands and removed the lamps and wrapped the seams with electrical tape, no more condensation. If they issue a recall I just peel the tape and bring it in.

I had a similar problem with my wife's VW - the Hair dryer works to get the moisture out - but - after it "looks" clear - you might want to blow in some cool, dry air - because if you seal it back up (at high temperature - after the condensation is gone) - when the interior cools back down, the moisture in the headlight will condense again...

No Coat Hangers, they can scratch the inside of the polycarbonate lens. Buy a magnet on a telescoping rod, most auto suppliers sell them. The powerful magnet will hold the metal wires and allow you to extract the bulb quickly and easily. I already did this more than once, it works every time.
