They light up well there has been no issue with their performance or level of illumination

I have not yet had any problems with individual bulbs malfunctioning or with water breaching the integrity of the units exterior

So far these led bars have held up reasonably well for being budgetfriendly counterparts to the namebrand versions

There was no specs or wiring schematics provided thats simply something you would have to accept in exchange for not spending much money
