Few ways depending on how much you want to spend.
1. Upgrade the bulbs in your existing with LED/HID. I have used kits from these guys in the past and been pleased.
Here Disadvantage is they aren’t road legal and you would have to swap them out come MOT time.
2. Change to an aftermarket light unit from Transporter HQ
Here which would give you the LED DRL look. Still regular halogen bulbs though so you would need to run same as above to get a good output. This style of light will often have projector units rather than reflectors which work much better with HID’s etc. I run similar units in a T6 and they are ok quality wise but in OEM.
3. Third option is to add full factory LED lights which will be very costly and a headache to get coded up. Sure someone more clever than me will have done it though. They are awesome though.
Good luck with the new van, sure you will love it.
