can anything be done to improve the very low headlight beams on 2001 f350 sd's. thanks.

 

I replaced my bulbs and saw a decent improvement.

 

A few things things. One, bulb replacement like twags said. I have Silverstars in mine and they are brighter.

Two, upgrade your wiring. The stock wire is too small IMO, and can't carry enough amperage. Upgraded wiring will make the lights brighter. Kits are available, or of you're good with wiring, just use some 12 ga or 10ga wire run directly from the battery (fused of course) to the lights, and use a relay triggered by the stock wiring to activate the lights. Kits available here: http://www.puredieselpower.com/catal...ade-p-111.html

Three, you can upgrade your actual headlights. If you have the older style, upgrade to the clear style like this: http://www.puredieselpower.com/catal...ks-p-1327.html If you already have the clear style, you can upgrade to the '05+ style lights, like this: http://www.puredieselpower.com/catal...cks-p-252.html

I have the '05+ lights, heavy duty wiring, and Silverstars in mine. The light is so much better than it was when everything was stock.
