Your profile says you live in San Francisco area. Is it possible that you don't drive in dark areas very often? The city never gets dark like it does out in rural areas.

 

LOL! We live in the country (but still on the peninsula). It is dark, dark, dark out here. No lights of any kind. Plus we're in the mountains, so we get the the low clouds that are basically fog when they are laying on the ground at altitude. I have the fog lights on more than off. It's not unusual to have less than 100' visibility.

 

If there are low clouds there is always a sky glow. The SF Bay area is really large with pockets of dark sky and pitch black unlighted roads. I can still notice the difference in the LEDs vs halogens. If they had been a $1500 option I wouldn't have ordered them but I didn't even realize I was getting them. Happy I did though. They really light up the road.

 

 

I always change my bulbs out to better Halogens. We live in the country and it's dark out here. As for longivity in Ontario DTRL are mandatory, I have a Honda CRV which uses a reduced headlight beam as a DTRL. I replaced the bulbs with higher output 4 years ago and they still are fine.
I have found the best source of bulbs are from Europe I buy mine from Power Bulbs in England mostly Philips or Oshram.

I don't know about the whole bulb matching the housing thing but the output is much better then stock.

 

Be careful if you are increasing the power draw...last time I tinkered with light bulbs, I melted the harness and ended up needing a whole new assembly. Granted this was a 2003 Focus.

 

Thankyou for bringing reason into this...I see so many folks on the roads while working with cheap HID/LED kits that blind everyone.

 

Yea i thought of that they go from 55watts to 65 watts,Its the Lumens that are increased by 1/3 approx.
I don't think for now the Hi Beam going into the Fog Lamp is a good idea,I know Heat is a Issue.

 

I don't think I'd put those hi beam bulbs in my fog lamp. Frankly, I bet it would melt the factory fog light housing. I installed the Sylvania Zevo bulbs in my fog lights....no additional heat and better light output. I should also mention that I don't drive around with my fog lights on when it's not foggy or if I'm not in inclement weather.

Bulb quality these days varies greatly, from crummy Chinese stuff to the few good ones still on the market.
Here are a couple of good choices.
The best H11 bulb is ( ). It will make a moderate improvement, not a transformative one.
I don't know what the better/best H9 is today.
If you want to improve the high beams, get ( ) (despite Amazon's advisory that they won't fit) and trim one of the base tabs on these new bulbs as shown (HIR bulb base modification) . They produce a great deal more light than the original high beam bulbs, but are the same wattage, so there's no risk of damage to the truck or its warranty.
