Spot lamps advice

Hi all, I'm looking to put some spot lamps back on my disco 1. I've had them on previously but unfortunately I had to take them off after someone bumped into them and the bumper needed to be fixed. I've still got the brackets and there is one set of wires with 2 connectors (pictured).

I would like to get some new lamps off paddock spares - ( https://www.paddockspares.com/da4088c-8inch-100w-spotlamps-chrome-back.html) but in the picture each lamp has 2 connectors so I'm a little confused as my present wiring only has 2 connectors and not enough for the 4 shown in the pics. Any advice would be greatly appreciated as I don't really want to get into wiring (not my strong point) and it surely should work somehow as I've had lamps previously?

Thanks in advance for any help!

Update - wired in a second wire after a call to paddock spares! Problem solved now waiting for the new lamps to turn up!

Yes, I did notice the ad said "excludes wiring kit". You've got two choices really when wring two lights in, wiring in series or wiring in parallel, also you can probably earth them through the mount, if mounted on the steel bodywork, or you can have a separate earth wire. Personally I'd wire them in with individual earths, in parallel, through a relay switched via the high beam relay, if there is one, or else connected into the high beam wire to one of the high beam lights. Be good for other members if you could tell them how you did it!
