PFL rear lens cluster LED bulbs

[moredun]

I got caught out without any rear lights the other night after heavy rain, miles from home at 23:30 (only number plate lights working). By the time I got home the off side light was working again but both lens clusters have water ingress.

While I have both lens clusters out, I was wondering what replacement LED bulbs people are using and I'm I correct in thinking the T20 (7443) bulb is a direct replacment for the Side/brake light?

 I have the Philips LEDs for the rear tail lights and some generics for the third brake light. I would only trust the Philips brand whenever possible. You can cut your amp demand by a good amount going with LED bulb replacements and the instant on has some benefit as well.
