For my 08 f150 i want to replace the interior and exterior lights with LEDs (except for the headlights i have HIDs), and have seen people talking about adding resistors or similar flash boxes so bulb out notifications arent triggered, cruise control still works, etc.
My two questions are, where can i find a guide on what bulb types fit where, as well as where i should buy the LEDs from? But more importantly when replacing the exterior lights, what do i need to do and for what lights to avoid having those issues? I've been doing some homework but am having a hard time finding clear cut answers

 

What I bought are listed in here:

They all plugged right in with zero issues. The interior ones are so bright that I've thought about turning the flanks around backwards because they're light turning on the sun and they're a little TOO bright for me at night haha. I want to say that ones people have issues with are the front turn signals and maybe some others, and mostly high powered ones, but all things electrical go over my head so I could be wrong.

The manual has all of the bulb types listed. Which bulbs are you planning on doing exactly, every single exterior bulb? Or just all interiors, license plates, cargos, and perhaps reverses? And what model/trim level is your truck? If you want to be extra "safe," you can just get exactly what I got.

Front maps are 194
Rear dome is 6418 and needs to be approximately 45 mm long
License plates are 194
Cargos are 921
I want to say reverse are 921 as well, but that's the only one I'm not 100% positive on, all the others I am.

 

Reverse is a 3156.

Front sidemarkers 194

Front signal/park 3157 amber

Rear brake/signal 3157 clear

Yer '08 does not have bulb-out warning.

For a flasher you need a Tridon EP-27 to eliminate hyperflash.

To fix potential cruse not working issues you may need to load the cargo light circuit.

Lastly - IF you are running POS cheap chinglish PnP HID's, shame on you fer being so ignant and uncaring of yer fellow motorists

Seriously - consider a proper retrofit - www.theretrofitsource.com

MGD

 

There ya go, MGD knows just about everything a person needs to know

He's even got them Triton V3's that are worth as much as a small mortgage

 

Do you have any suggestions for loading the cargo light/3rd brake light circuit? ive heard of some people using resistors, but i dont know what size, parallel or series, and what have you, and i didnt get cheap hids, i got them through hidnation.com who ive seen has a good rep

 

Get 'em MGD!

And just so I add something relevant to the post, I'm pretty sure you need a 25w resistor for the 3rd brake light (if you need one at all). I've put LEDs in my last two F150s and didn't need a resistor for the 3rd brake light. The resistors for the turn signal lights front and back should be 50w.

 

What brand HIDs ? 90% of the aftermarket HIDs are junk over priced crap. But what MGD mainly means is putting HIDs in stock reflectors cause unwanted glare every where. Mainly high into oncoming motorists eyes. The focal point of your stock dual filament halogen is way different then the single arc of an HID capsule. That arc is hitting the reflector bowl in the wrong places sending light where it isn't suppose to be. Take it how you want, we just like to keep people informed

 

i see what you mean now, wasnt clear before. but right now no, i will be getting projectors in the future however.

 

you mean 25 amd 50 ohm resistor? and wired in series i take it? every one seems to say you need one too for the 3rd brake light for the cruise control which would be nice to still have.

 

and the Tridon EP-27 should eliminate the need for resistors for any of the turn signals right? sorry about all the posts im just scatter brained from school work

 

No, they should be 25w (10 ohm) and 50w (6 ohm). The 25 w (10 ohm) should work for the 3rd brake light. No need to wire them in a series. You would need one 25w resistor for the 3rd brake light. One end to each wire (I think there are only 2 wires for the 3rd brake light). But like I said, I haven't needed a resistor for that location in my past two F150s. You can always try it without the resistor first to see if it is even needed. The 50w (6 ohm) resistors are what you will need for the turn signals (unless you end up going with built in resistors).

Here is the link to the exact resistors I just put in for my rear turn signals:

 

Yes, the flasher would eliminate the need for resistors in your turn signals.

 

Good most people take it the wrong way and get defensive.

ok thanks for the help guys! Im new on here, moved up from Cherokees in October and it's like starting all over again, i appreciate it this should have me on the right track
