Pros: VERY bright, very sticky sticky pad on the rear, lots of useful connections to suit most bulbs types for connection, very nice colour of light very white with just a hint of blue but not enough to make it dimmer like blue led's are, would defo buy again, think this has got to be my 8th or 9th now, used everywhere on the car, interior light front and rear, 1 more in the boot, one in the glovebox, even fitting some on door underside as puddle lights they are so slim.
Easily light the floor outside the car when doors are shut, and interior light goes on such as when disarming alarm etc
The light is VERY spread out, nothing like a spot as such but very very even light spread.

Cons: I am really struggling here to be honest, maybe the wire could be a little more substantial as it's hard to solder in if you need to connect that way, but no bigee

Other Thoughts: Would definitely buy again as I always do, coming back for more as are all my freinds who have seen these, described as a searchlight when they come on whilst inside the car, they are very bright, but I don't see the point in a lot of the dim interior lights, they only have one fucntion so should do that well, sadly many don't, these babies do!!

Bottomline: If you need light in a compact unit that can be left on forever and a day without flattenning the battery get these.
I have now also put some in my garage.

Pros: Bright, really bright! It rivals if not outperforms Edison bulbs - at least with my Corolla. Quite easy to install, mine fitted perfectly and seems to be there where I sticked it.

Cons: None really, though minor complaints could be made at the flimsiness of the cables and the main connector - i.e. the one which connects the lamp with the chosen cable/adapter. Also, White appears to have blueish tint - could be a bit more warm in colour.

Other Thoughts: I used this lamp both with the motor on and off, also - with the motor on idle and all doors left open (less series resistance of all door switches) - and the lamp survived voltage changes, but to be honest - I did not try to torture it for hours or so... In my car opening more doors makes the lamp brighter - it translates into no driver, just resistors in series.

Bottomline: Easily recommendable item. Could be cheaper.

Pros: Bright, bright, bright, bright! Did I mention bright? Better whack in another couple of bright bright brights to get the characters up to 500!

Cons: One more festoon adaptor for a longer bulb would be good, plus an adaptor for the larger bayonet bulbs. Bluish white light.

Other Thoughts: Really useful for many applications, especially in motorhomes. Take the sticky backing off to let the air circulate, and glue them in place of Halogens or whatever. Connect them in series for 24V applications.

Bottomline: Really bright light in an easy to use package at a good price!

Pros: exact right size for my car to replace the original bulbs. Fits perfectly in the opening in the ceiling. Much brighter than original bulbs.

Cons: -None of the adapters fitted my car so I had to solder the connections.
-slightly on the expensive side comparing it to the price of bulbs. I was still running original bulbs after 8years, so with all likelyhood I only had to change bulb once or twice in the lifetime of the car= still cheaper.

Other Thoughts: Lots of people have admired the brightness and tint. Now I can actually read comfortably in the light, or search for that lost € coin from the floor.

Bottomline: You want more light? -> Buy them
You want better colour of light -> Buy them
Want to be cheap and change bulbs -> don't buy them.
