I hate the beam pattern of the notoriously well engineered 9004 bulbs and was wondering if anyone here has used driving lamps/lights during normal nighttime driving...I understand most companies do not recommend them to be used under normal conditions and they should be used like high beams...but i was wondering if anyone here was able to use driving lights sort of like fog lights? any opinions are welcome(even the bad ones)...thanks...

 

No, you should use driving lights along with high beams, and fog lights along with low beams. Their beam patterns are completely different. Now I suppose you can aim the fogs up to be sort of like high beams, but they have a very diffuse pattern so the light won't go far. As for using driving lights in fog, you'll get so much glare it will hurt more than help.

 

gotcha...i understand the beam patterns with fog and driving...i wanted to get the extra range of the driving lights but not be offensive to other drivers...i was wondering if anyone has tried this...thanks again...

 

i use the catz msx driving lights and they make a significant difference. i swapped out the factory fogs for them and it was totally worth it.

 

what's the law say about using these lights on public roads? Are we allowed to use fogs on regular roads? I live in TX.

 

Driving lamps do not have a proper pattern. Since they do not have horizontal cutoffs, you would have to aim them extremely low to avoid excessive glare. But in doing that, you would have negated any benefits of having driving lamps to begin with.

 

Does anyone know if driving lamps like the Hella DE Xenon's are legal to use with your regular low-beams?

 

gotcha...thanks for the accurate and specific answer that i was looking for

 

Any auxiliary lamp with a driving light beam pattern would be illegal for on-road use with your low beams.

 

Are there any legal alternatives in using auxiliary lamps w/low beams?

 

Sorry boss. That's why it so important to have good headlamps.
