They are exceptionally bright and easily visible as turn signals. I am impressed by both the brightness of the forward facing LEDs as well as the remainder, which reflect off the inside of the housing nicely. The 1156 version works just fine with our cars, you just have to file down one of the stubs on the side of the bulb. I know this sounds a little shady but it fits perfectly once you do this. Since these do not have built in resistors I add them separately for an extra $5. After this they did not throw any codes.

*I would not advise buying the 18 LED version! I bought these perviously (in amber) and was not comfortable with the brightness.

*Swithback LEDs usually utilize the 1157 bulb types because they have dual contacts on the bottom. This bulb type (1157) will not work!

*In case you find a switchback bulb type that does work (which I haven't): Keep in mind that switchback bulbs only light up half of the LEDS at a time, so a 60 LED switchback will be about as bright as a 30 LED bulb.

*Lastly, for those of you who are thinking about getting bulbs with 60+ LEDs, remember to read the width dimension! Some of these will not fit inside the headlight housing.

Hope this helps!

Great info thanks

Khoalty actually sells the switchback in 7507. Their lights are 120 LEDs ! So 60 amber 60 in white led at 400 lumens. Sounds pretty good to me. Both bulbs are only 25 and both resistors are 9. I think it's a good deal.

I am going to check my turn signal and make sure the bulb type just to be safe and might go with khoalty

^hmmm I'll call and ask them before my order ships.

I went with the 21 LED one that uses larger, supposedly brighter LED chips.

Stock 1156 is 1.04 inches in diameter and 1.77 inches long.

The ones I got are 0.8 inches in diameter and 1.88 inches long. Idk if so, but I think my bulbs will just reach farther into the actual headlights

Btw, to those looking..

1156 and 7507 are equivalent except for the nubs in the bayonet base. The bulbs will not fit in each other's sockets, but you can interchange 1156 and 7507 bulbs if you file off one of the nubs.

1156 has nubs directly opposite from each other:



7507 has nubs offset at an angle:




It was mentioned earlier that one could "modify an 1156 to fit." ^that is what you need to do.

Great info guys, really looking forward to seeing some reviews

I just ordered these from modmy3
http://www.modmy3.com/bmw-e90/bmw-e9...gnal-bulb.html

They will require resistors which i also ordered

when i install them ill post up a review and see how bright they compare the my current white bulbs (halogen)

Im hoping for the best *fingers crossed*

Got my lights and installed them today. Its really bright outside still but already I can tell these aren't as bright as my stock halogen turn signals. They're not horribly less bright, but its certainly noticeable.

I have my car coded to not check for resistance in my turn signals so I cut the wire for my the load stabilizers that came with them, and they flash at the same rate as stock. They fire and shut off very quickly, which is really what I was aiming for.

I'll post pics / night time photos and maybe a video too.

Cuba, thank you for your order and review!

If you guys still need help sorting through all of the bulb info that's out there, feel free to PM us or email us and we'll be happy to help you out! We know there's so much confusion surrounding E90 bulbs. It's mind boggling haha.

Have a great night!

I think this is a pretty interesting answer.

Also,

ddmtuning has a bulb w/ 60 3528 LEDs that puts out 420 lumens. I'm giving it a go for my rear turn signals.

I wasn't a huge fan of the ijdmtoy ones (i think only at 360 lumens like the modmy3 ones), so I might do a comparison when they arrive.

Finally got my ddmtuning lights in today.

They're just as bright as the halogens. Love them. Actually planning on picking up a set for the front turn signals now. Definitely brighter than the ijdmtoy ones.

will try to post pics soon
