Jammer, you still don't get it.
LIGHTS BURN OUT. Happens every day and if you spent a full hour looking for one light, you probably were wasting your time and failing to mavigate for a good 55 minutes.

Each product is designed for a specific purpose and they accomplish that purpose very nicely. Your problem is that you want something which you can't or won't buy. Nothing wrong with the product, you just don't understand how or when to use it.
An hour looking for one light, ROFL. That ain't navigating. Or piloting. That's a fixation.
