Will this bulb work as a replacement for a 7443 Brake/Tail light? Does it dim and get bright for brakes?

Got this specific light for my 2007 Mazda 3 hatchback for my brake light but unfortunately it didn't work so what I did was to use it for my back up light. It's nice and bright.

No, it is single brightness. 7440. Also, it is white light. You want to use red for brake/tail lights to match the color of the lens for best light output.

Hey Robert, The bulbs we send out for this item are actually the 7443 duals so it would work for your application however as Joshua mentioned, red bulbs might work somewhat better for brake lights.

It is a direct replacement for the 7443 bulb. If your Acura takes this bulb it should work. The bulbs worked fine except they were not very bright until you put on the brakes. I contacted Putco tech support and they told me a resistor was required to make them light up to full power. After doing a lot of research I could not find anywhere that a resistor would work as they described. Instead of spending more money on resistors I chose to return them because I was worried no one would notice the tail lights at dusk. Instead I purchased a set from Vleds. Quite a bit more money but a lot brighter.

read other comments not recommending it either, dimmers are a rheostat unit, the light may work, buy two just in case; also, this is a large bulb, 85w, but the light output is VERY bright.

Yes, these bulbs have two brightness levels. They have two contacts on the bottom. The tail light is the first brightness; the brake, or stop, light is a brighter second brightness.

Yes it should but the wiring harness they send you probably won't work correctly. When I hit my brights I only had one come on until I rewired it

I bought these in dual filament 7443, yes they work. However, the brightness between the two filaments is not as apparent as the OEM bulb. I would say when the brakes are applied the OEM bulb is twice as bright, these LEDs are brighter than OEM when running, but when the brakes are applied maybe only get 20% brighter. Not too much difference...

No, I think not. Turn signals rely on incandescent bulbs to flash at the correct rate, but brake lamps are modulated differently here ... by an electronic circuit which is not dependent on resistance through the bulbs, but instead is self-regulated by the circuit itself. I have a brake modulator on one of my motorcycles with LED tail lamps and, if anything, they enhance the flashing because of their shorter illumination/decay times. They will flash faster and go completely off between flashes whereas a bulb will only appear to pulse bright-to-dim-to-bright repeatedly in a dull display. Go for it!

This bulb should work. It's fairly easy to install also, just take your time.

I do believe it does, I am not too sure on the Year brake between the earlier model. but if your light looks like this all you do is pop the old one pull the plug and connect the old connection might look different but it should work just as good.

Not really ... overall they are brighter but the difference when braking is not as significant as the regular bulbs

no clue. but you may google info to get the manufactures number to make sure this is the right bulb. i had a different mirror and this bulb worked for it.

Poor brake light performance, they're only very slightly brighter in break-light mode than basic, parking, tail light mode. To me, that's a safety issue. I don't use them, threw them away. Save your money, it's junk. You'd want really BRIGHT(!) LEDs in brakelights b/c they light up a tiny bit faster then incandescents - which just might save your rear end. For taillight, parking lights they are useless except for longevity and electrical consumption - should you forget to turn your parking lights off, and your car doesn't have an auto shut-off.

I checked Sylvania website they say that this bulb will fit the backup lite and center brake light/ and lower brake light and rear turn light, rear tall light bulb is 3057, / front turn light is 3457A, so you need three different bulbs.http://www.sylvania.com/en-us/applications/automotive-lighting-systems/Pages/lrgallbulbs.aspx?year=2008&qual;=&model;=1772&make;=68

Hi,Thanks for the question if the vehicle already has an auto dimming mirror, orhas a harness that has power then this will work, you should test your vehicle to check before confirming the order.Thanksautopartsotys

They should, but don't work for brake lights / running lights because there arent 2 stages of lights. Mine burned out quickly, I think because of wiring

Hi, it's 2 bulbs and could be bright enough, depending on the wattage of bulb you use. I actually returned mine because it didn't fit my application.Mike

First off why did you change the bulb? Great upgrade to LED. If you had a brake light problem to begin with it may be your B.L. Switch. If neither of them work it must be up line. Try testing the bulb ground the outer housing and put 12v to each terminal if they work it is your vehicle test light those sockets. If you have power while the blinker is on then make sure they are not frozen in place spray a lube in the socket and use a non conducting push rod to loosen the springs. Hope this helps. Also if you change front and rear you need a low voltage flasher.
