I think they suck in the toyota *edit* ALL *edit* applications where the DRLs (daytime running lights) burn the low beams... so they are used almost all the time.
If they were using the hi's, then I would be less annoyed, because I drive alot, and the low beam always goes, and the whole bulb needs to go.
My old van had 9004's... not great but one pair only used the lows, and another pair used the high filaments.
On my Cavalier, I modded the bulb socket, and bulb base holder, so 9005's were in the low beam and high beam lamp positions.
