I see your point...Yes they do throw a lot of light further...The only thing I can say is that before the LEDs at night in reverse, i would need to tap my brakes while baking up due to the fact the stock reverse are weak and I needed more light...

Now it is not a problem backing up at all at night..I can use either the mirrors or the camera no problem 100% better... I would also say it is a safety feature..i dont think anybody in a parking lot would have any doubt you were backing up!

They do make some 360 degree bulbs...which might throw more light around the truck as opposed to further away... my concern with this is that the LEDs are so bright in might wash out the camera picture...

Both from ebay, they are different types but look similar. The 7.5w fit in reverse lights, no issues. The 13w fit in the cargo lights with no issues. Both are a huge upgrade to stock, the 13w are just ridiculous! I didn't try, but it appears the 13w would be too long for the reverse lights.

Side note... I just installed front 3157 LED signals and 194 side markers, nice surprise was they didn't require resistors.

Please post links to ebay for all three items below or wherever you bought them from.

I ordered the 3157-R45-T 12VAC/DC and they Hyper Flash

What am I missing...is your truck a pre 2011?

Thanks,

Fred

Damn, I thought I had that listed on here... Yes it's 2010, I looked prior to installing and couldn't find any flasher around the interior fuse box (where all other vehicle's I've owned have been located, though this is my first Ford). I did a good bit of research and never found an answer if/how 2010 differ's from 2011-up.

Here's what I ordered:

If I change out my rear bulbs, I may run into an issue with flashing and cruise control.

I think 2010 was the last year they did it through the interior fuse bus...the 2011 and later do it through the "Computer" and the clicking sound when you turn is an electronic noise...at least that is what I have read...

Still doesn't explain how you got yours to not hyper flash without resistor or relay...

I'd love to know the reason to this myself, it was all stock other than some Rigid Light bars when I picked it up a few weeks ago. I'm not complaining that it just "works" but there was nothing on the bulbs themselves that would eliminate the need for a flasher or resistor. Hell, the flasher speed didn't even slow down when I installed them.

When I get home, I'll go "listen" for the flasher and see if I can find it. Maybe it was for some reason swapped out for an electronic one.

Could be something with the Light bar...I agree that is great it works....

I am getting the cargo lights you recommend as well...

I notice Outlaw is selling a "Complete Kit" including Blinkers for Raptors...I got a question to them regarding the Hyper flash...

Interested to know what you find out...glad the blinkers are working...
