I have a 2004 545i...have a high beam malfunction. Is this the same bulb as the low? The lights are non xenon ... Where is the best place to get a new bulb or should i replace both sides with a better light? What does everyone else do? Put Xenon bulbs in? Is replacing a bulb as simple as any other car? Thanks!

 

In a non-xenon application, your bulb is dual filament, meaning hight and low are in one bulb. Replace the affected bulb.

 

all of our bulbs are error free or a full refund will apply
