The bulbs arrived on time as expected, one of them had some small shards of glass inside of the sealed bulb and I contacted them regarding it. They replied they would send a replacement at no charge (havent received it yet but should be here in a couple days) The other bulb that had no issues is currently installed and working perfectly. Ive given them a 5 star rating regardless of the 1 bulb as their customer service is exemplary !

Light replaces the existing lamp, same fit and turns on when required. Package and lamp does not provide country of manufacture and one of the poles twisted when tightening the connection causing me to wonder how long the lamp will work. I will not repurchase this brand again. Aircraft Spruce offers other selections so I will look here first.

Just whai I needed. Fits right, no trouble hooking up. Comes with the brass screws so I could get rid of the old screws. Better price than my local FBO, so Im happy.
