Wiring ? Lalizas bow light

[Refueler]

The yellow female is too small. The male blade is too large for regular connectors

Very strange ..... all lights I have had - when spade connectors - have usually taken red and blue .... (yellow could be used by 'closing up with pliers !).

What about solder a short wire to the light connector .. then you can use whatever connection you like ??

Here is an example of what you may need, ignore colour, it can be Red, Blue or Yellow as previously stated. look at the size of the push on bit. (Blade width you need).
Female Blade Terminals - 0.5 - 1.5mm² Cable (Red)

No need to close a yellow connector, the yellow only indicates the wire size, not the terminal size.

These lights are very common, there is no need to modify the terminals, he just needs to use the correct terminal.

There are also 9.5mm terminals, although not so common.

I'd expect the OPs light to have the ubiquitous 6.3mm terminals on the light. Zooming in on OPs pic it looks like the terminal should fit, with a push. It certainly doesn't look like a 4.8mm terminal. It does look like a cheap and nasty terminal though, perhaps it's a Chinese size

AKA quarter inch

Fold the wire back to form a V or U then crimp it into the male spade.

Actually this is not good practise, it weakens the connection though admittedly it's very commonly done.

If you're using the correct terminal for the wire you can't get the wire in if it's folded. (as you know)

Back to the OP, this might have been an opportunity to put an LED fitting there. As it is, the item chosen doesn't look very rugged, more akin to a car interior light than something that will withstand a bow crashing through waves, hostile marine environment etc.

The crimp has 5.5 stamped in the side. If that is the width and the blade on the light is 6.3mm it is clearly the wrong size crimp. Get a crimp of 6.3mm and the correct wire size hole for the wire you are using. At first view it looks as though the crimp is fully on the blade but if you magnify it, it isn't. Its just resting on the end and not fully slid home.

I saw the 5.5, but there is no such thing (that i'm aware of) as a 5.5mm spade.

I wondered that but Google suggests "the yellow color of the connector typically indicates that it is suitable for larger wire sizes, specifically for cables with a cross-sectional area of 5.5mm²."

This would cover the 4-6mm of a standard yellow?

I think that the 9.5 are usually for relay terminals?
Just a further thought. Perhaps the OP should be aware that some of these spade terminals can be exceeding tight, not the first time I have had to resort to the assistance of pliers to pull them apart, or just give that little "OOMPH" to get on.

I actually have a box of crimp terminals that do have different spade sizes ! I agree that the colour of insulator is for wire size ... but they all do have alternative spade sizes as well ...

Typical Festoon bulb fitting ......

Typical Festoon bulb fitting ......

I know. Probably first used in a 1950s Ford Popular interior light.

Apply 14+ volts to that filament then give it a flick with your finger, see how long it lasts. (14v is typical charge voltage on the 12v bus when batteries being charged).

1. You should not be using car festoon bulbs in nav lights ... even though many people do.
2. Suggest you check the voltage across your car gear when engine running and alternator is fired up ... no different to on the boat unless you have such as Sterling or similar charge modifiers. Even then the modifier is only delaying the cut off to get a few more % charge into the batterys ... the voltage is still similar.

I have never had a festoon fail as you imply in any of the nav lights on my boats ... failure has usually been the end caps have become detached after years !

The Femail Yellow is pushed onto the Male !!

You can actually just make it out if you look carefully.

Ah! What I thought was a solid wire going into the spade is in fact the bright edge of the male spade.

But OP has now clarofied that the Female is sitting on top of the Male !! Ooh La La !!

MY thoughts as well but if it was 5.5 and the male 6.3 then it seems to fit the photo very well. Too much of a co-incidence not to be the size I'd say. But never seen one that size before and I've worked in industry with crimp connectors all my working life. Don't remember ever seeing the size stamped on the side of one either though.
