I wanna change my halogen bulbs with the led aftermarket bulbs, do I need 2 or 4 bulbs????? and yes I bought the cheep model w/o the nice leds....I know their the H13 bulbs....

 

I want to do the same. I looked and there are four H13/9008. I thought I'd try the Sylvania ZXE bulbs. Which ones are you looking at?

 

Do you need dual function bulbs, for hi and low, or just single?

 

thats what I'm trying to figure out, is it 2 bulbs or 4

 

Looks like we need 4 dual function H13 bulbs from what I can tell.

 

Curious to see how they turn out and look! Please do share some pics with us after you're done installing them

This should help you out.

 

Interesting. Would worry about longevity.

 

I run them in my 7.3 truck work awesome. Thinking about getting them for the 17 soon!

 

How long have you run them?

 

I had LED headlight bulbs in my Tundra for 6 years, they were amazing. Never had an issue.

 

Problem is choosing which brand to buy. Amazon has several to choose from.

 

I ran the Opt7 brand in my 08 F250. I loved them. I have them still and i will be buying a second kit to install them in my 17 here soon.

 

Whats the concern for worry? LED's have been proving their superiority over conventional bulbs for years now. For example, no filament to burnout or vibrate loose, less amp draw, low heat. The only "real" issue is aiming a retro kit so its not blinding to on coming traffic.
