Bonus Info: The headlights are very easy to replace, because that's a safety issue. Can't have drivers unable to replace their headlights when on the road.
Same goes for the tail lights, except replacing those bulbs requires a little more work, pulling off the red lens, that requires your GENTLY pulling rearward the tail light assembly so you don't snap or break a small retaining clips that keeps the red lens flush with the rear quarter panel. If it does break the clip can be replaced.
Once you remove the tail light lens, access to all the bulbs is very easy.
Of all the lights, the fog lights are the most challenging bulbs to replace. (As you can see in the video.) But with patience you can do it yourself.
I for sure would NOT take your CR-V to a dealer, one who might tell you the entire assembly/housing is what's replaced when a bulb goes out. IMO that would be a FRAUDULENT representation.
I think he is talking about the many little DRLs that goes around the headlights. I can see where they are probably not individually replaceable.
