In fact, all light sources are checked in the process of allowing a vehicle to move and EACH of them (external lighting) must obtain a separate certificate of approval. As far as the technical review is concerned, the "manipulated" lighting of the license plate is treated as so-called. "minor defect" and allows to pass the test positively. Even not so long ago I wrote about it on the electrode, there is even a link to the recipe:

Here we have another aspect of the matter requiring an emphasis: We already have a legal basis that the whiteboard lighting lamp does not have to meet the approval conditions. However, LED bulbs that are replacements of "mechanical" ordinary light bulbs (ie those with W5W, T10 - matching the holder) very often shine like torches - especially the older generation. And here you will not be able to rely on the mentioned recipe, because the approval is different, and what else is the visibility of the board highlighted with such candles

The same applies to the cab backlight, or can it be attached to the overview?
Once a policeman attached me to the road. I had such a blue "ambient light" inserted into a lamp above the mirror, glowing together with positional ones. He did not like the fact that they were visible through the rear window while driving. "Yes, yes - you are right, sir!" And that's it.

Not true. No provision in this regard uses the POWER of a light source. The light bulb must be homologated, it also has the scope of light specified by the regulations.

The volumes were already written on this subject, but in short: someone once wanted to increase the power of classic, good-looking H4 bulbs. Zuwagi on the technological limitations of the filament material was not then possible to raise the filament temperature (almost immediately the filament burned out) that someone used a longer filament, with a thicker wire to thereby enlarge the surface of light emission. At the same operating temperature the filament had more power - but technologically it was a dead end, because the light was stronger, but a disproportionate part of the electricity was converted into infrared radiation - that is simply heat destroying the construction of the reflector. A much more important disadvantage of such a bulb is the shape of the filament: because it is much longer it ceases to be a point source of light as in an approved bulb. Partially "goes" so beyond the geometric center of the reflector and such a spotlight just starts to dazzle.
Technological progress has allowed us to follow a different path - the shape of the filament is as it should be, the increase in light power is achieved by increasing the temperature of the fiber. The filament shines a lot brighter (whiter light), and additionally it allowed to increase the efficiency of the bulb - because the emission of infrared radiation is lower. This is just the idea of light bulbs "+ something there". It's easy to guess that the higher the percentage, the temperature of the filament must be higher. Unfortunately - this is related to its much lower resistance to the failure of the vehicle's charging system - mainly voltage spikes and continuous exceeding of the nominal voltage in which such a bulb can work. Probably there are signs of dissatisfaction about their rapid burning out. I personally do not complain. I care about the charging system and I do not notice a special shortening of their life compared to the classic H4
- how he checked the steering wheel clearances. How good is the selection it looks good illuminates the table legibly, but it CAN NOT dazzle others, even the diagnostician told me that there is no problem.
