I've already fit LED's everywhere I can (footwell, interior, side lights and numberplate lights) which I had from my Saab.
The head lights are also up-rated ones from out my Saab (can't remember what make, ring blue I think) with my dipped beams being the Night Breakers.
I couldn't get to my fog lights so they are still standard...
I would like to fit the HID's and maybe evn a set of DRL's too if I can find an ignition live in the engine bay area.
It's only an hours job to swap the bulbs back round again come MOT time (access is tight on the Laguna's)
I have interior leds in place of the regular filaments ,everywhere except the drivers door light.So many other circuits are controlled off that it doesnt like a low resistance led in there

Fog lights, on mine you can get at just about thru the front plastic wheelwell covers if you take out the screws.
The drl's on mine.I turned off the cicuit(via computer options) that enables them at all.
They are now wired into the sidelight bulbs ,with leds the reduced wattage is no more than normal sidelights would have ,so Im running 4. bulbs on the sidelight circuit.
Im not advocating bulb switching to pass an MOT,if you wanna do it thas up to you.
Me personally I will switch mine ,when the time comes for the Irish version of it just in case..I also dont wanna be a pain to other road users /get stopped by the lads in blue,hence the R bulbs.
It could be that addons in MOT land are np..then again here in Ireland,there is a "we are the govt " generated clampdown on naughty boy racers for MOT/NCT.
If youre 17 your damn lucky we let you on the road in your 1000 cc panda.How dare you tart it up and try and frighten grannies and mechanics with your loud exhausts.
The girls are much more sensible

,aside from the 100mph dash from Dublin airport into the city I had with a couple of headlight flashing air stewardesses .
Yeh they won

, my testosterone had a reality check at the jump the q of cars at traffic lights by going into the oncoming lane :d.
Ive seen threads for tuning boxes for example where posters get thru the MOT with them fitted,me Id prefer not to chance it.
There is a post/thread by Ahmed24 on the vagaries of the renault drl's and the use of pwm in the circuit.Hes the guy with a rs replica project.
