Just got headlights. Need help with the lighting.
Just got these headlights and when i plugged them in, low beam turns on by itself and on high beam only the high's work...
my question is, how do i make the low's turn on with the high's when i switch to high beam. any way to easily do this with out cutting alot of wires.

Since they are "plug-and-play", and your stock headlights are designed so that only the low or high beam will function at any given time, there is no easy solution without doing a fair bit of modification to the wiring.
then you will have to splice that wire. and use your basic electrical skills to figure out how to make one turn on and the other at another. compare it to your old lights.
did anyone ever do this before.. could use some info.
my guess is, i could use a diode on each headlight, current flows one way with low beam, and in high current flows from high and also to low. i think this might work, but anyone know which type of diode i could use, all i got are the diodes used for alarms.

There are kits available (though they aren't designed specifically for H4 setups), or you can use your own relay(s) to wire it up yourself.
You basically want to tap into the high beam positive wire to use as your relay trigger, and then splice the relay's power output into the low beam positive wire. Ground the relay and connect the power feed to the battery (don't forget a fuse), and you should be all set.

Thanks for the info. I have that harness, threw it somewhere in my garage because i thought it was the wrong harness but looking at it right now and its the right one.
Low beam projector isnt that bright.... Should i retrofit Hid? kinda broke right now though... sucks ***... lol. but for temporary, would blue or white light bulbs be brighter then the stock looking ones because right now the light is stock looking.

any way to clean the projectors? they seem fogged up and the light is dim. also, whoever has this type of headlight, what color bulb should i use on the projectors so they could be the brightest and easy to see at night.
H3 for the projectors and H1 for high beams... i was thinking about getting amber bulbs for the highs and i guess im getting white for the projectors... is it possible to lower the high beam so the lights would be aimed lower, so i could drive with highs and lows at the same time.
We need a full pics of the poster before this thread goes any further

Most aftermarket projectors are not good for light output. Use a normal wattage OEM type headlamp bulb or maybe a superwhite (not blue) bulb. If you purchased these headlamps for light output, you most likely will be disappointed unless you retrofit an OEM projector into the housing.
I've had the Denji projectors before. Light output sucked and when it rained it was really horrible. Also, my experience with aftermarket housings have been hazy glass in a short amount of time, mositure inside the housing, had black headlamps in a 98 civic which began to bubble over time.
Good luck

Silverstar bulbs are much brighter and whiter than stock. That's what I use and it is a big difference over stock bulbs or other 'hyper white' bulbs that I have tried.
