Today someone asked in other topic for additional nigh light for spark. We have some extra landing legs with 2 flashlight for front legs on amazon/aliexpress  but each require battery AA so the weight of dron is bigger and its then wrong balanced. In other topic i mentioned about OTG cable and usb led bulbs. Unfortunately i dont have small light bulp like this so will not try this in fly.
But if someone want to know if OTG + usb led works - here is few photos from test ofc on amazon/aliexpress u can find bigger led bulbs or even try led strips with usb jack

OTG adapter like mine is 0,5$, usb bulp is < 1 $ from China, so we can add light to Spark for not more than 2 dolars.

Is this useful ? dont know - need to try  at night.

Now that looks strange.
No wonder it is off balance

Can this take off?I want to add police lights in my spark....

Yes it can. No problem its only 15 grams (lamp + adapter)- it is notebook lamp so is big and low power - 0,5 W. If u attach something smaller but with more power will be more light - Light from this lamp didnt help Spark to keep position. I will try some day with better lamp

I have one of those OTG adaptors, as soon as my Spark gets back from repair, amma try this.

Thanks!

Just take care not to brake the micro USB socket in spark.... I would use something shorter

Sure - i advise against using so long "tail" i just tested if it work: spark + otg + led usb. If someone want to use something like that in fly  i also advice smaller light source

Now Spark looks like a firefly.

I would not recommend you fly with this extra lighting. It will have a bad influence on the balance of your drone. I think the light is not strong enough to fly in dark place.

I would stay away from flying with back door open due to dust and humidity.  Secondly, if you still want to try to fly with such lighting.  You may find other options online where you could Velcro a smaller light to the bottom of your drone.  I saw another post here earlier this week ... https://forum.dji.com/thread-116758-1-1.html

Firstly - i dont fly with that lamp - i just made a test if it work with led powered from spark back usb. I nn lights in my bird dont fly at night, especially with so big and putted in his "ass" . Secondly, if u are interested about take-off with my lamp i try to record second video today for u. But according to some post above - i dont use that light in fly,  like was said, back cover must be open with that and its risk of usb malfunction with it.

Any worse for dust and humidity than the vents on the top, with the mainboard right inside?

Those vents are for the cooling fan.  They were designed to be there.
