   your reason is bullshit. it is also illegal

   You could but it’d be wiser and easier to just get high quality fog lights

   This is rather easy to do. On one set of headlights locate the connector to the high and low beam lights. With a volt meter or automotive test light connected the negative to body ground. Use the positive probe to determine which lead is positive for each lamp. Get a high current (about 25 Amps) 50V or so diode. Connect the banded side of the diode to the LOW BEAM positive wire. Connect the side opposite the band to the HIGH BEAM positive wire. A diode works as a one away valve for electrons. When the low beams are on the diode will block power from getting to the high beams. But when the high beams are on power will flow to the low beams. You only need to do this at one set of headlights as they are on a common circuit.

   If you can’t find a 25 Amp or higher diode you can get a 25A 50V Full Wave Bridge Rectifier from Radio Shack; OOOPS! I mean “The Shack”. Connect one of the AC inputs (sometimes indicated by ~ symbols) to the high beam circuit. It does not matter which AC input you use and you could use both if you wanted. Connect the + symbol of the bridge rectifier to the low beam positive circuit. A bridge rectifier is simply four diodes arranged in a pattern to turn AC into DC. You are just using it as a diode.

   if you want the road lit up better , that tells me that the headlight
   lenses on both sides have delaminated and you have cloudy
   headlights.
   if they are really bad and your headlights are like cataracts the
   only thing you can do is change the headlights.
   but if they are not that bad but bad enough to where your headlights
   are insufficient then you can go either to walmart auto department and
   there they have a chemical process for clearing up your lights and making them like new……

   or……..

   you can go to a body shop and have them use the same chemical
   and their buffers and clear up your headlights that way.

   so its either a fix or repair but the lighting system is not
   designed to light up both low and high beam at the same time.
   should you wire it up and make it do that , you would melt your
   wiring and maybe cause a fire.

   the least that would happen is that you would get a ticket for
   being too bright.

   but fix your cloudy headlights and you dont have to mess with
   rewiring the high and low beams

   wow, i bet you’re that person that we all have driven past who doesnt turn off their highbeams when another car is approaching, aren’t you? that car will NEVER pass any state inspection with the lights wired like that. good luck, its bullshit and its illegal.

   not only can you set up your high and low beams headlights to work at the same time, you can also increase light bulb voltage to 13+ volts to make the existing bulbs brighter.

   the Daniel Sterns web site have complete wiring diagrams and instructions, it also sells kits (minus the wire) to accomplish this. the kits include hd relays, switches, connectors etc.

   use this link to gain more info, look under “special option for 4 lamp systems” for answers to your question. (the ability to use high and high/low beam is controlled by a third relay and a dash mounted switch so you can select this option when you need more light).

   hope this helps
