Landing Light Circuit Overheats?

[Lukon]

My landing light quit on me the other night on approach after working for fine at taxi and takeoff. I cycled the switch and it felt like a breaker not wanting to engage. After I was on the ground taxiing fir a bit, I was able to cycle the switch and it worked fine again. Is it pulling too much power? Would replacing it with an LED landing light solve the issue?  Is there a reasonably priced option out there?

probably just old breaker/switch.  I've got a similar problem with my position lights breaker.  I have to make certain not to try to turn off the switch when I want to turn it back on again.  Needs replacement.  I really want to just rewire with separate breakers and switches...

LED draws lots less current.   Amazon sells a PAR 46 LED work light manufactured by Wheelen.  For your tractor of course.

Breaker switches do go bad.  My pitot heat switch went bad like that.  It trips after about a minute or so.    

In any case, aside from the switch, Go ahead and get an LED and don’t look back.  You’ll be happy.

I replaced my landing light and fuel pump switches with new old stock ones I found online. Easy fix.

@Lukon  Somebody reported the same challenge yesterday... Wednesday... 

When you don’t feel the click... the CB switch is telling you that it has worn out...  there is that spring loaded over center thing you can learn a lot about...   Mooneys have a few over-center mechanical things that work best when adjusted properly and are replaced when worn...

 

PP thoughts only, not a mechanic...

My LED landing light was doing this.  I found that the wire insulation had rubbed trough and bare wire was rubbing against the negative terminal and shorting out intermittently.  Fortunately, whoever wired it left some extra wire so I removed the bad portion of the wire and installed a new ring terminal.  So, at least double check the wire going to the light before replacing anything.

The other good thing is the landing light circuit is in the realm of preventive maintenance.

I had this same problem. I switched to an LED landing light in 2015 and have never had the circuit pop again. The current draw seems to be WAY less.

I switched to LED in 2014, and it's only been turned off twice since then--halfway through a pitot static check and once during annual.

Can anyone recommend a good, economical LED landing light?

This is probably the best solution.

These are examples of the right size for a PAR46:

This one is very similar, supposedly brighter, and less expensive:

I purchased the AeroLites Fusion PAR46 and couldn't be happier...
