hey i have a 2001 blazer obviously and i noticed driving at night my lights a pretty dim now i know some of this is caused by my soundsystem but thats usually only when the bass hits whats the best thing i can do to get a brighter light is there better bulbs i can get or is it just lask of power that i have running through my truck

 

Try cleaning off the connectors on the bulbs...sometimes, they can build up corrosion that will cut down on the power traveling through the wiring. Also, over time, the bulbs will dim as they age. Try a silverstar bulb, they are freakin' bright

 

hey thanks where could i find these lights at does the company have a website

 

AutoZone has them, I'm not sure about Advanced Auto, and I think that Wal-Mart carries them too. Although I have never been all that impressed with the life of a silver star bulb, nor the light it produces (bluish white). Living in Central NY, the silverstar bulbs glare WAY too much on the snow to be beneficial. I would only consider them in applications that already have a very poor headlamp beam pattern (93-97 Dodge Intrepid to name one).

You could also run a relay setup that would feed direct power to your headlamps, but that would require some rewiring and some new connectors. Here's a good site explaining why and how to use relays, Daniel Stern Lighting - Relays. I had done this on my old 94 Intrepid and it was a night and day difference on a very poor headlamp design. It would be much more promenant on a good headlamp design. There is A LOT of good info on that site! Have a read through it all, there are very good explainations and all of them hold true.

 

Turn off your stereo.

Seriously, turn it off and see if that makes a difference. If so, you have bigger issues to worry about. A bigger alternator would be a good start. A Red top batttery would also be a good investment. (drawing a blank on the name of the battery at the moment, even priced one for my truck last night). Arrrggggg......

 

Optima.

Yeah, if you have healthy stereo, then your problem isn't the lights, but the power distribution (alternator & battery). Getting a deep cycle battery should help as well as getting a higher amp alternator, but if you are running a big stereo amp, your system may need a capacitor to even out the bass hits. It'll make the rest of your electrical system last A LOT longer if it doesn't see voltage fluctuations of that magnitude.

 

so a new battery and a cap should help what size battery

 

Battery size goes by cold cranking amps. 700-800 should be plenty.

Not a cap, a high output alternator. $$$
