4. The Department upon approving any such lamp or de-
vice shall issue to the applicant a certificate of approval to-
gether with any instructions determined by the Department.

5. The Department shall publish lists of all lamps and
devices by name and type which have been approved by it,
together with instructions as to the permissible candlepower
rating of the bulbs or the beam intensity which it has deter-
. mined for use therein and such other instructions as to adjust-
ment as the Department may deem necessary.

231. REVOCATION OF CERTIFICATE OF APPROVAL ON LIGHT-
ING DEVICES. When the Department has reason to believe
that an approved device as being sold commercially does not
comply with the requirements of this Article, it may after
giving thirty (30) days' previous notice to the person holding
the certificate of approval for such device in this State, con-
duct a hearing upon the question of compliance of said ap-
proved device. After said hearing the Department shall de-
termine whether said approved device meets the requirements
of this Article. If said device does not meet the requirements
of this Article it shall give notice to the person holding the
certificate of approval for such device in this State. If at the
expiration of ninety (90) days after such notice the person
holding the certificate of approval for such device has failed to
satisfy the Department that said approved device as there-
after to be sold meets the requirement of this Article, the De-
partment shall suspend or revoke the approval issued therefor
until or unless such device is resubmitted to and retested by
an authorized testing agency and is found to meet the re-
quirements of this Article, and may require that all said de-
vices sold since the notification following the hearing be re-
placed with devices that do comply with the requirements of
this Article. 1?he Department may at the time of the retest
purchase in the open market and submit to the testing agency
one or more sets of such approved devices, and if such device
upon such retest fails to meet the requirements of this Article,
the Department may refuse to renew the certificate of approval
of such device.

232. BRAKE EQUIPMENT REQUIRED, (a) Every motor ve-
hicle, other than a motorcycle, when operated upon a high-
way shall be equipped with brakes adequate to control the
movement of and to stop and hold such vehicle, including two
separate means of applying the brakes to at least two wheels.
If these two separate means of applying the brakes are con-
nected in any way, they shall be so constructed that failure
of any one part of the operating mechanism shall not leave the
motor vehicle without brakes on at least two wheels.
