High + Low beam at same time?
System boggy today, search failed.
Adding relays to headlight wiring on '99. While I'm at it, is there any problems with wiring the bulbs so the low beam stays on when hi beam is activated?
I've done this on others vehicles, and the extra light is very nice. But it does generate more heat....
Just want to make sure the Ford headlight assembly can withstand it. Using stock '99 for now, will eventually upgrade to early 2000's clear assemblies.

There is a unit out there called a Britebox that does this, but it's quite expensive at $90. The headlight housings should be able to withstand the heat however I would think that you would be decreasing your bulb life as it wasn't designed to run both at the same time.

Yes, the housings can handle the extra heat but since the bulbs have both low and high beam together you will run the risk of overheating the bulbs!!!
I used to do this on chevys and it worked great, but they have separate bulbs for low and high beam so the heat isn't a factor. I wouldn't do it to the Ford headlights.

This will be my first time doing it with 9007 bulbs, I'll definitely let others know if there are issues. I have done H4's in the past with no issues, and the 9007 appears to be an equally robust bulb. 100W 9007's are available, so the fundamental design appears capable of withstanding the heat - unlike the newer H13's (as used in 2005+). And yes, I will be beefing up the ground wire and connections.
Dual filament usage will be used only on demand - I use it when traveling on bad/gravel roads with lots of undulations.

Riggz, thanks for the mention of the BriteBox. They offer many boxes to do exactly this for my truck and many others, so that is at least some evidence the 9007 will be capable of handling the heat.
I do all my own wiring so I won't get to try the BriteBox, but good on them for offering it!

No problem. Just remember that just because someone makes a product to do that doesn't mean it's safe for the bulb. This theory has been proven true with the Edge Attitude tuner and the 6.0L engine.

Slight tangent; anyone know where I can buy a connector that emulates the bulb side of a headlight connection? 2 or 3 pronged- two parallel blades, third one 90 degrees those and at 12 o'clock. With pigtail wires I can crimp connect to...

Not sure I've seen anything like that. What are you trying to accomplish. Maybe we could come up with an alternative solution. Maybe using some standard male spade connectors?
