Does anyone here know wher ei can get a higher output 3156 Signal bulb for the rear lights? cause i did something and the OEM ones is not bright enough..
Would the 3157 "dual filament" work?

I thought they were 7440's?

Anyhoo, if you're looking for something brighter, perhaps if you grab some crazy hyperwhites from any ricey shop they will shine through better. But if they're tinted blue, maybe not.

Also getting a dual filament won't do anything about increasing brightness, all it does is give you a way to power the bulb from two sources.

They are single filament 7440. I'm assuming you want the brighter bulbs for the stock tails that are red. Well Raybrig makes a hyper clear bulb that's 2x brighter than stock. It's not a coated bulb, but still there is a big difference. I have the 168 mini bulbs in my sidemarkers and dome lights, and the 7440 in the reverse lights. They look just like a regular clear bulb.

Try to see if the raybrigs come in that size. They're the best if you can find them. I thought 7440 because I have a sedan.
