Each life jacket light that has a non-replaceable power source must be replaced __________.
AI Explanation
You are correct, the answer A) on or before the expiration date of the power source is the correct answer.
This is because the regulations for life jacket lights with non-replaceable power sources require that they be replaced on or before the expiration date of the power source. This ensures the light remains functional and provides the necessary visibility and safety for the life jacket.
The other options are incorrect because they do not align with the regulatory requirement to replace the light based on the power source expiration date. Replacing the light at fixed intervals of 6 months, 12 months, or 24 months would not necessarily coincide with the power source's lifespan.
