The TB20GT, at least, has a TEST button for the gear lamps
So, probably, a failure mode where a lamp does not illuminate with the test button, but there is a real gear fault, is unlikely.

Adding a little lamp test button would be much more clever than forcing pilots to switch lamps while flying a busy traffic pattern, IMHO.
Adding a lamp test button can tell you if the lamp is broken, but if it is you will be none the wiser about the status of that gear leg.
I have wondered about those lamps.
Hello
Do you the reference of the bulbs that are inside the lamps? I think as per IPC the whole lamp has to be replaced?
Thank you
I think this is the light:
Part Number: Z00.N7922710202
Nomenclature: SADAR INDICATOR LIGHT 169507145-15
Zs.
Thank you. This is the whole lamp I think not just the bulb that is inside.
Soldering isn’t best option. It get’s hard and can crack. It should be crimped but by using proper tool and technique, it will never fail.
Anyway, using of those push-on automotive contacts without any mechanical protection is just joke.
BTW is it possible to extract that whole little panel with the lamps, as shown above, without gaining access to the back of it? I expected that to be an absolute bastard of a job.
If it can be extracted then anything is possible. If you can extract the lamps then you can see what they are.
