I have a rangehood with some lights for illumination. But they're expensive lamps, mains voltage, not very bright and they run hot. So I'm looking to remove and replace with something LED based. Ideally I'll remove the whole lampholder assembly and store them, and fit a replacement. To do so I'll need to connect to the existing wiring harness with two new plugs.
But I don't know the name to search for, and there are many different standards.
The lamps are 240 Volt AC. Both sides of the plug are designed to hide the metal contactors from accidental touch. One side is a round prong and a square prong, and the matching connector has round and square holes. Each block is 4 mm per side, though this is hard to measure, could be 20% off. They are mounted inside an earthed stainless steel rangehood.
As you can see there is not a lot of slack in the wire, so while I could snip these off there's no space to reconnect them. Also local laws allow me to "plug modules in internally" but not "rewire" so plugging is important.
The only other comment is that these are inside the rangehood and are exposed to grease and steam and heat. They're astonishingly clean given an age of ~8 years, with no tackyness or similar feeling, so I suspect I need plastic that is heat-tolerant.
Question: What are these called? And do I need a special tool for them - if so what is that called ?
