I got ill and tired of the left or the correct or BOTH lights going out and having to plough them dorsum on more ofttimes than always on my 2004. And non existence an extremely wealthy person, I wasn't about spending money on these expensive bulbs once or twice or e'er. Meanwhile my wife's 2007 with Halogen bulbs (which lit up the road only fine) was working perfectly with no such safety problems, and then I idea, hey, why not pop these chipped faded faulty headlights out and put in a pair of new clear Halogen mode units in mine? Happy I did. No more than troubles. Just information technology's not a directly plug and play solution, and then here'south what I can share.
First, I bought those female crimp plugs, the large ones that fit the 9003 H4 blazon bulb prongs. I took the Dark-green wire that feeds the fog lights and hooked that up every bit the running light (looking at the bulb from rear, it'due south the LEFT prong, the TOP prong is GROUND).
Beautiful, dainty and bright, just have to make sure to get out the fog calorie-free band on the headlight switch turned to the on position from now on, and so the headlight control works every bit expected. Low Beam handled.
Adjacent, if I ever wanted bright lights again, I'll need to use the BLUE wire which I hooked up to the Hullo Axle filament which is the prong on the RIGHT rear of the H4 bulb.
Here'south the Problem. The BLUE wire sends a LOW VOLTAGE feed then my Loftier-Beams are underpowered. This is because it'south designed to ship a "signal" only, to the HID brain works, when you select the Brights from the inside of the machine. It does light up the Loftier Beam filament, and since the Depression Beam'south are at present powered by the Fog lead which goes OFF when in High Beam mode (blue low-cal on dash), it functions every bit information technology should... I collection around like this using the High Beam equally day-time running lights and switched to Low Beam when it got dark.
LASTLY, I'm going to purchase a couple relays. I'll tap into the Side Maker light (orange, side of headlight) positive wire, and brand THAT the 12v Total voltage feed for the brights. And then the Blueish wire will trigger the relay and laissez passer the total 12 volts to the High Beam filament. At present we're done.
This post was designed to share a solution that price me next to nil, confirm that hey, you're NOT the only 1 who wanted to to do this, and confirm YES it can indeed be washed - even with no wiring diagram or degree in electronic wiring schematic reading (that post above gave me a caput ache).
Toll for a pair of halogen headlights assemblies nearly $130.00 shipped, plus wire connectors and relays about $40.00 plus $20.00 for a pair of bulbs, and you'll demand to spend about $30 bucks at the Toyota dealership for the twist-n-lock rubber round "lids" that keep dust out. The top of a two litre coke canteen with 3 holes drilled to allow wires through and a little silicone caulk fits those OEM "lids" perfectly.
The auto looks fantastic, lights the road like when my wife's 2007 was brand new, and it took near two hours to do (yep y'all have to remove the bumper encompass, run into YouTube).
As for Fog Lights, you have two options: You lot can keep yours, if you don't heed them coming on every time yous turn on your Low Beams, just install a splice-connect in-line... or install a fog light button on your dash and run a new ability feed to them.
My fog lights were chipped and croaky and I don't need/utilize them hither in SoCal so I chucked those and I put an aftermarket aluminum grille for $l in downwardly there.
