I have a 2005 Impreza RS wagon that has the H1 bulbs in it.

Anyone have any feedback on the H1 LED Headlight Bulbs?

Thanks,

Larry

I tried a set of LED H1 bulbs.  They did not work so back to original.

I generally run Cougar Motor LED bulbs off of Amazon.  They generally last 1-2 years.  You could check Diode Dynamics and see what they offer, they'll run about $200 for a set.  I've never had a Diode Dynamics product fail, and I have a lot from them.  Fantastic customer service as well.

are you sure its H1? in europe hedalight lamps are H4....

in any case, i went el cheapo with these, like 35$, thye lasted 2 years.....

look in thier shop, maybe they have the H1 you need

H1 bulb are single-beam.  H4 bulbs are twin-beam High/Low.

that much i know.... but how do the us headlights work? separate bulbs for low and high? 

Single H4 bulb, with 2 filaments.

good, so where do the H1 go?

Found this in a 2011 NASIOC forum:

So it looks like the following Subarus use H1 low beam bulbs:
2004-2005 Impreza
2003-2004 Baja
2000 - 2003 Legacy

Yes my 2005 Impreza has to bulbs the H1 Low beam and a separate Hight Beam bulb.
