OK, so I am interested in changing out my current stock bulbs in my 2010STX to LED's. But I look on line, OK look on super bright LED's website and see many options. Can Bus bulbs, resistors, etc etc.
QUESTION: how do you know what bulbs to get?
I want the side marker lights, front and rear, turn signals, front and rear. High mount stop light, reverse lights, interior dome light.
I hate to spend the $100 and then have the wrong bulbs!
Some say if you have the wrong one you have to add a resistor, or it wont blink. You have to order a certain bulb...yadah yadah yadah.

i am lost!
anybody offer some help??
THANKS

 

look in the vendor section I think someone has a complete kit you can purchase for the f150

 

I got the numbers for the bulbs from the manual in the glove box. Took those numbers and put em in at dx.com and got everything I needed. Puddle lights took a lil more research.

 

Think puddle lights are 33mm festoons.

 

31mm festoon is what I put in them. 42mm for the inside.
