2nd that for the PhillipsWhat lights do you have? H4’s H7’s?
I upgrade my dipped H7 beam to Phillips 130% and that has made a massive improvement. Would had gone for the 150% but wasn’t sure what the life would be like (the 130% versions I got are around 450 hours).
Not sure you want to go down the illegal route (assume you mean LEDs in a non-LED headlight) as if you are involved in a bump they could pick up on that and not pay or blame you.
Have a search on here as there have been many topics that discuss options.

Loads of threads already on H4 light options, I don't intend to go over all that, I just saw a Transporter HQ video on Youtube which suggests that they have a new LED "bulb" which works in their projector bulb, they say it will go through an MOT, but admit it is not legal on road. They say it'd very bright but does not dazzle other motorists.
I know from previous threads that this is a contentious issue, I'm just pointing out that THQ are offering it, make your own mind up!
Fit hid lamps to the dipped projectors on your THQ lights, Mikem posted some pictures from his conversion, not only work well but are cheap compared to the brightest LED lamp alternative.
