Hi all, Has anyone successfully improved on the standard front fogs on a pre-fl mk.3?

I'm not interested in them looking cool or coming on when I corner or indicate, I'm interested in them being usable in fog as I often have to navigate dark roads in the Pennine hills. Currently the standard Osram 46212 35W bulbs are so dim as to be seriously useless. I'm better off with dipped beam.

Previous cars had 55W fog bulbs, but I keep seeing warnings about the chance of melting plastic housings.. obvs don't want that!

Anyone used things like Nightbreakers with any degree of success? I'm not bothered about colour, either, so would equally happily go down the yellow route.

You need CANBUS Friendly LED bulbs - did this on my FL Scout. Made a huge difference.

Expensive, but worth it!

Blimey!

I'll keep them on the radar, but a bit rich for now.

Are they plug-and-play, or any further adapter needed?

Just noticed the Smart are still listed as 800lm, same as the standard ones. Hmmm..

Okay - maybe I didn't understand the brief. Yes, there are definitely brighter bulbs out there; its a case of trying to find a bulb that doesn't exceed UK / European standards. The LED's will be more intense and the light frequency is difference on that example (6000K).

UK lighting standards legislation has fallen far behind the technology as it still uses wattage as the criterion to describe the power of a bulb - hence the OP mentioning 35w fitted as standard. That will refer to a "conventional" tungsten filament bulb which was all that was available when the law was written; superseded by halogen bulbs in the 1970's or thereabouts. Now we have HID and LED bulbs that use a lot less current to generate prodigious amounts of light so a 35w LED would produce enough lumens for a searchlight.... That's why the gubbinsment is now belatedly talking about "reviewing the situation" - just like Fagin.....

Hehe, that's now my earworm for the afternoon!

In other words, think about the bulb in your bedroom - you'd have had a 100W filament bulb in there, whereas now it'll be an LED bulb around 12-14W. As above, the lm (lumen) output is far more important.

Do also, as above, bear in mind the temperature of the light. Using the fog lights in my Leon really annoyed me, as the headlights were a cool white LED, and the fogs were yellow halogens!
