TEXT: Dear Ms. Jones,

We are thinking to sell an optional rear spoiler, in which a high-mounted stop lamp (HMSL) is built, because the optional spoiler prevents the signal of originally equipped HMSL from being seen.

Since an electrical connector is removed from the original HMSL and connected with another HMSL in the optional spoiler (See the following drawing), the original HMSL never lights up. In a word, the original HMSL has no function in a car. Therefore, we think it is allowed to leave the original HMSL equipped in a car.

(DRAWINGS OMITTED)

Please let us know your opinion towords this matter.

We are looking forward to your reply.

Very truly yours,
