I've never seen a 65 Mustang with back up lights.  That does not mean they were not available as an option or on a GT.  If they came on a GT and you do not have them, try checking for their wiring under the back valence.  A PO could have deleted them.

That said, I would install them as a nighttime aid in backing.  I do not know what that entails, but it will involve a bunch of wiring work as well as two holes cut in your rear valence. - You could check a 66 factory wiring pamphlet for the exact wiring needed.  Wiring is available virtually everywhere in Mustangdom.

If you want stay stock, leave it alone.

My 64.5 had them too.  When it was time to replace the rear valence, I went without them.

A 1965 factory GT car should not have back-up lights. They were an extra cost option in 1965. It also should not have rear bumper guards (in the way of exhaust trumpets), rocker panel moulding or power brakes. It should also be an A or K engine code car.
As for the Rally-Pac, through very early 1966 the proper one should be the high profile one.  6K tach for the A code engine and 8K tach for the K code engine. So it’s possible to have an early 1966 factory Rally-Pac that is high profile. Factory 1965 Rally-Pacs came without the words across the middle. I haven’t seen those reproduced.
Apparently the 64 1/2 factory Rally-Pacs DID have the words in the middle, the factory 65’s (or most, did NOT), and the dealer installed and parts counter ones, again, DID have the words on them.
Since, I think, most of the Rally-Pacs were dealer or parts counter sales, for your car, a high profile repro with a 6K tach is correct as can be.

I believe there are various tach adapters from MSD that allow the use of their ignitions with factory style tachs.  Another possibility, as not sure how the. SD rally packs are in terms of quality.  Their other stuff is pretty hit or miss anymore. 

Considering I got rearended by night with my coupe... definitely I think I’ll go for LED in the tail lights.
LED bulbs?
I’ve seen that they offer them in white or in red... what’s the way to go?
I read somewhere about blinker issues, what about it?

Unless you want sequential these are great, super easy to install, basically plug-n-play.

You can probably get them locally through Dallas Mustang.

Took maybe 20-30 minutes to really brighten up turn signals/brake lights.

Steve Buzek has LED backup lights on his 67, more like mini headlights on the rear when in reverse.

Here's the link/path to SMP

ive seen many many 65s with reverse lights..i always just figured maybe they added them?...

So when you say LED, you’re talking about the big LED board C5ZZ-LED ?
Or about the LED bulbs SD-1157-RFB-RD?
Is that the way to go?

Another question for specialists:
About Fog lights... why are there some white ones and some amber ones?
What’s the difference?
What’s factory installed on an early GT?

Fog lights...Amber lenses are a modern iteration. Correct would be the clear/white ones. But, as with anything Mustang, make it yours and be happy.

Again, do a search on this forum. There are a couple of threads with lots of experienced recommendations. But to kind of answer your question, it depends on its use.  The simple single LED “bulb” will shine directionally like a flashlight. Probably good for turn signals. The bulbs or plates with LEDs in every direction are meant to shine like a 100W bulb with no lamp shade. These are also brighter. Probably better for the tail lamps. All the light assemblies have refractors that refract (reflect?) the light out towards the lens. Brighter is better these days.

Edit to add: The LED strips or boards with multiple LEDs are probably what you were thinking of when you wrote “plates”? Like the kind in tail lamp assemblies, sequential or not? I was thinking plate as in the metal headlamp LEDs from Mustang Project.

Not quite true on clear fog lights only.  Actually both were available though amber was less common. 

Really?  I guess ya learn something new every day. Thanks.
