Advice for newbie with wiring up led/pcbs to power

[bad-lighting]

Hello,

I'm a newbie. Apologies for my stupid question, probaly repeated many times before.

I'm trying to build two of Znomit's dinotte style light for dynohub, but I think I've bought the wrong pairs of led+pcb and optics from cutter. I can't see:
• on the one pair how to fit the optics snugly onto the pcb, because the optics have pins that are just wider than the locating holes on the pcb
• on both pairs how to connect wires to the pcb without the wires getting in the way of a snug fit between the pcb and the optics, because the optics are the same diameter as the pdbs.

Can anyone tell me if I have bought the wrong stuff?

Will I now have to get tools out and cut grooves in the bottom of the optics so wires can pass through them without lifting them up?

This is what I bought:

Light 1:
- XPGWHT-L1-0000-00G51 R4 Bin
- Cutter-XPG20STR
LXP Optics to Suit Cree XPG
- Oval ±19° x ±11.5°

Light 2:
Optic
- Lisa2-RS-Pin-XP-G
Cree Xlamp XPG Led
- XPGWHT-L1-0000-00G51 R4 Bin
- Cutter-XPG10SRO

With many thanks!
