What bulb for tail light bulb?

194 and 168 are both wedge-base bulbs of the same size, so either one will fit, but a 194 will be about 20% too dim. A 168 is about a five-watt bulb, which matches the W5W (wedge base, 5 watt) designation you see in your owners' manual.

I have 194 LEDs in this position and they are about three times brighter than what I took out they kind of look like the annoying brake lights on some new cars that are so bright the brightness makes you stay back from the car so your eyes don't hurt I think that's the logic on the new cars now my 0709 Prius looks the same way people don't pull up very close to the back end like they did two months ago because the little 194 bulbs when you do that the car behind me everybody's red that's behind the windshield of the car behind me when they pull up that close It lights them up and that's me sitting with my foot not on the brake just sitting there that's not brake light activated that's just the 194s on first step of the switch car sitting behind me they don't do that much anymore.

 

Well, that would be a T10 (mm) wedge-base LED replacement that somebody labeled '194' by mistake. If it's three times as bright as a real 194 then it ain't a 168 either. It's just a random LED replacement that'll go in the same socket.

 

No the t10 is too long I have those here in that little 194 red square bucket that the 194 168 sits in You don't have enough height to get anything worth a crap in there I even tried what other wedge base what are they 902s or 920s they're too tall they'll knock the little silver square that's attached to the outside of the red square bucket of the housing right off and now they're stuck in your in one of my housings off the little square piece of silver that sits at the end of the square bucket that the 194 goes in if your bulb is too tall it'll knock that loose now if your bulb is white or 6,000k you have two slots showing white out the back of your lamp assembly so I put in red LEDs that are real bright but I don't know their wedge base 194 based plug sticking out the bottom of them but they don't look anything like a 194 would normally look these are a larger diameter about the same height so on and so forth and they're red so they won't show white out the little two slots where I knocked off the chrome square oh well but their bright is all get out that's all that mattered here

 

If it's tubular in shape (as 168 and 194 are), and it's 10 mm across (as 168 and 194 are), it is a bulb in the T10 family (as 168 and 194 are).

If there's some LED-retrofit vendor selling something he calls T10 and it's too long, then it's just another example of the LED-retrofit vendors playing fast and loose with the bulb designations, and it's a far cry from being the first one.

 

I don't know but what I have here listed is t10 the base looks a little bigger than the 194 and the 168 and it's a little taller and I thought all t10s that I've seen kind of mimic this and then it has a on the end of the wedge base or on the center of the wedge part there's a circle in the middle I don't think the 194 or maybe the 194s do have that too but it's larger The t10 that I'm looking at actually mimics the base of a 3157 almost but anyway no matter yes all of the LED bulb makers play fast and loose with everything that is a fact. Usually I can just get them to send me a sample they're pretty good about that and then I can see what's what but on these cars there's just a couple of bulbs and not much really to have to fool with.

 

I believe it is in the owner's manual for the tail light replacement bulbs there's a chart or a list I'll try to make a copy of it today but posting it s not really going to happen All you have to do is remove the little plastic curved piece in the trunk or you access your tail light bulbs and you'll see the turn signal 7440 or 7443 and the 194 wedge bulb at the bottom they're just sitting there The guy at advance Auto will bring out the right bulbs and put them in for you they're in stock.

 

Use a 168 wedge bulb at the bottom; a 194 will be about 20% too dim.

 

If you do go to AutoZone and talk to the dude about the bulbs for your marker lights Tell him to show you the Sylvania ZEVO 1W Amber for the front and red for the rear wedge bulbs they will blow the 168's or any incandescent slap out of the water in brightness and being seen Good luck.

 

When replacing incandescent tail lights with LED, they should be about the same brightness as the the incandescents.

There is nothing worse than following a bozo that has replaced their incandescents with super bright LEDs.

Bright tail lights also demishish the differential effect of the brake lights too.

 

Yep just like all the new cars makes people stay back a few more feet .very irritating. A few years ago I was more interested in blackout like a military vehicle . Hit a button complete darkness perfect for eluding and evading . Then ya hit 65 or so and you light up the night . Tis too funny.
