Hello all,

From what I've searched and read, the 3rd break bulb for my 04' Screw is a #921 bulb. Now what I was wanting to know if the two reverse bulbs on the left and right side of the break light is the same 921 bulb?

I've seen that the lower left and right reverse bulbs are #3156.
So is it the same for the above ones to?

In a nut shell what are the three bulb numbers on my 3rd break light, 921 for all three or 921/break and 3156/reverse?

Many thanks guys and gals!

Thanks 88 racing!

I'm going to order two high mount reverse led's.
(#3156)
eBay has got some great prices on these led's!

 

i think your a little confused there buddy. bulb size 3156 is the reverse lights inside your tail lights. the white lights on both sides of the red third break light are just cargo lights and come on when you open your door or via the scroll on your dash. all three bulbs inside the third brake light are size 921…

there's also a reason ebay has great prices, they are usually poorly soldered and do not put out much light.. but sometimes you do get lucky with them.

 

wtf?

 

Shut the front door!

I had for some reason thought the third brake light was part of the reverse lights (two outside lights).
Just went out and pulled the light. Yup all three bulbs 921.

Well I'll be!

My momma always said, "Life was like a box of chocolates. You never know what you're gonna get."

 

Don't feel alone, I have ran across other posts where the OP's thought that the 3rd brake light was part of the back-light system, so, your not alone

 

Don't buy LEDs from eBay. They'll burn out in a month.

 

Buy your LED's from Jon_To! They're made in USA...
