i have a classic and put fogs on it but they dont seem that bright what watt bulbs should be in them ive put some 100w bulbs in but are pretty dim

 

Fogs are shi'ite on Impreza. They just have enough power to pick out the side of the road (as they're designed to)... in yellow lol.

Should have fitted 'driving lights' in their place, which light up the road ahead when on full beam - much more useful for 99% of the time.

I'm not sure what the fog bulbs are - I think the maybe the same as headlight at 55W . If that's correct, then I wouldn't put 100W in as they'll draw nearly twice the current and could run into problems with the Subaru's marginal lighting loom...

 

If your fogs end up too bright they'll be less effective in fog as the light will just bounce back at you. Fogs are rubbish in any other weather anyway as the low, wide beam pattern meant for illuminating the road edge and white lines either side doesn't usually extend any further than 5-8m or so, making them useless when you consider stopping distances at even 30mph are listed as 14m. Only pillocks use foglights in anything other than fog, heavy spray or heavy falling snow anyway. If however you were after driving lights to aid night driving on unlit roads then you bought the wrong lights as these have a much longer and narrower beam pattern through different reflector design.

 

Yea bin the fogs and put in driving lamps, on the cheap side is Hella 500's or the expensive end Piaa xt 80's

 

corradoboy has summed it up perfectly.

And slipstream has given you great cost-effective - and not so, lol - driving light options.

 

thanks for all your help guys yea wanted them for unlit roads as even my main beam arnt that good unless on full beam but yea the bulbs i brought from ebay 15 quid they are 100 watts these ones Xenon Upgrade Fog spot light Bulbs H3 100w super white on eBay, also Bulbs Lenses, Lights Lighting Accessories, Car Tuning Styling, Cars, Parts Vehicles (end time 08-Feb-09 09:48:35 GMT) but are so dim a nice white/blut tint but dont really light anything up ;-(
