A problem I have is the inability to see the gear transit light on in daylight.

No doubt lots of options, but what suggestions in terms of a quality light bright enough to see when it operates.

Dom,

 

In my aircraft I chose to use adjustable-shutter push-to-test incandescent indicator lights for really important things like gear locked lights and gear motor running (transition) light.  The shutter can be adjusted to a pinpoint at night and full bright for daylight.  The push-to-test function helps avoid a misinterpretation of a light out.  I have been using these since the first flight in 1996 and 650 flight hours later, they are still working without replacement.  I do carry spare bulbs in my glove box.

 

I cannot find these lights at Aero Crafters, Aircraft Spruce or Wicks online catalog although I think any avionics shop could get them.  They are expensive.

 

Another option would be to use a super bright LED with the brightness controlled by a dimmer circuit or a switch  that uses two different resistors (for voltage match) to control day/night brightness.
