I decided to upgrade my rear numberplate lights.
I ordered
these.
They're T15 W16W. I then found some text on the light unit that says W5W 8W #168.

From the limited research I've done, they will fit in the sockets (I think), but will they damage my electrics?
I know nothing about electrics! Volts, amps, watts, ohms. It all baffles me!

Nah it'll be fine as long as it fits nice. Might be a bit bright tho.
I got white LED ones. First batch went all flashy after a few months. Got sent free replacements. Look pretty nice more modern blue/white than oldie off yellow.

Thanks Judderod!
I'm slightly worried about the brightness level.
I'll try them and if they're too bright I'll get the right ones.

Get IndigoLemon's thoughts as well. He has LED rear bulbs. They may throw the brake warning light.

they mess up the back-up light circuit on my type S. it needs to 'see' a given value of resistance on the circuit or it thinks bulbs are out or the circuit is compromised.
to solve this you need to put a resisor inline to fool the circuit into thinking all is as it should be.
something 'like' this
but not this

I have LED number plate bulbs (not canbus) in mine, no problems at all - straight swap and running sweetly. The pain in the bum is the led brake light bulbs, and here is where I reveal my OCD tendencies ...
With filament brake light bulbs, and the LED spoiler brake light, the spoiler always lights first. It's only a fraction of a second quicker, but you notice it, and this bothers me. So I bought some LED brake light bulbs. Sadly, this triggers the 'brake lamp' warning circuit, and so, I did this:

I swapped my rear plate bulbe to LEDs without any canbus gubbins with no issues, mind the car has only been driven for a mile and a half since then, that was 2 years ago.

This ^ Pushki, your bulbs are listed as "Canbus" - so yours have a resistor in-line already as part of the bulb so they draw the same as regular filament ones

Thanks guys! I was just worried about the wires melting or the fuses blowing.
I should have them in a day or two. If they're no good, I can put the old yellow bulbs back in.
I have reverse and rear fog LEDs already fitted without any problems.
I've no immediate plans to swap the rear/brake light bulbs. Maybe when they
need replacing.

Probably a bit late now, but Philips do some fast response brake/tail lights. They are brighter and light up something like 33% faster, the idea being whoever's behing you knows you're braking sooner, hence effectively increasing their stopping distance.
