يقول تقرير الفحص إن المصابيح الأمامية والمنبه والمساحات سليمة.

This is a very common Arabic word order pattern.

Arabic often uses verb-first order:

• يقول تقرير الفحص ...
• literally: says the inspection report ...

In natural English, we usually switch it to:

• The inspection report says ...

So here:

• يقول = says
• تقرير الفحص = the inspection report

This verb-first order is completely normal in Modern Standard Arabic.

This is an iḍāfa construction, often called a genitive construction or noun + noun possession structure.

• تقرير = report
• الفحص = the inspection / the examination

Together:

• تقرير الفحص = the inspection report
  or literally report of the inspection

A few important things about iḍāfa:

• The first noun usually does not take ال here.
• The second noun can be definite, and that makes the whole phrase definite.
• So تقرير الفحص means the inspection report, not just an inspection report.

Here إن introduces a clause meaning that:

• يقول تقرير الفحص إن ...
• The inspection report says that ...

After verbs of saying/reporting, Arabic very commonly uses إن to introduce the reported statement.

So:

• إن = that

It is very common after verbs like:

• قال = said
• ذكر = mentioned
• أعلن = announced

This phrase means the front lights or more naturally the headlights.

Breakdown:

• المصابيح = the lamps / lights
• الأمامية = front / frontal / front-side

So literally:

• المصابيح الأمامية = the front lights

Arabic often uses a noun followed by an adjective, and the adjective comes after the noun.

Also notice agreement:

• المصابيح is plural
• الأمامية is also plural and definite

The adjective matches the noun in:

• definiteness
• gender
• number
• case

Because in Arabic, adjectives normally come after the noun they describe.

So:

• المصابيح الأمامية
• literally: the lights the-front
• naturally: the front lights / the headlights

This is the normal Arabic pattern:

• noun first
• adjective second

Compare:

• سيارة جديدة = a new car
• الكتاب الكبير = the big book

Because it refers to one item: the horn.

So the list is:

• المصابيح الأمامية = the headlights
• المنبه = the horn
• المساحات = the wipers

English also mixes singular and plural in lists:

• the headlights, the horn, and the wipers

Arabic does the same.

المساحات means the wipers, usually windshield wipers in this kind of context.

Its singular is:

• مِسّاحة or ماسحة depending on usage and context

In car-related language, المساحات is the standard plural form you will often see for wipers.

So in this sentence it refers to the car’s wiper blades/wiper system.

This is one of the most important grammar points in the sentence.

In Arabic, non-human plurals are very often treated grammatically as feminine singular when they take an adjective or when a pronoun refers back to them.

Here we have non-human things:

• المصابيح = lights
• المنبه = horn
• المساحات = wipers

These are all inanimate objects, so Arabic commonly uses a feminine singular predicate adjective for the whole group:

• سليمة = sound / intact / in good condition

So even though English would think “they are sound,” Arabic often uses a feminine singular form with non-human plural items.

This is very normal and idiomatic.

It is best understood as agreeing with the whole list as a set of non-human items.

Arabic frequently treats a group of inanimate things collectively, and the predicate can appear in the feminine singular.

That is why:

• المصابيح الأمامية والمنبه والمساحات سليمة means
• the headlights, horn, and wipers are in good condition

Even though one item in the list, المنبه, is singular masculine, the overall inanimate list can still take this feminine singular predicate.

Literally, سليم / سليمة can mean:

• sound
• intact
• undamaged
• healthy
• safe

But in this car-inspection context, سليمة means something like:

• in good condition
• working properly
• sound
• not defective

So it does not mean “healthy” in a medical sense here. It is describing the condition of car parts.

Because Arabic usually does not use a present-tense verb to be in sentences like this.

In English:

• The headlights are fine.

In Arabic:

• المصابيح سليمة
• literally: the headlights sound/intact

The meaning of are is understood automatically in the present tense.

Arabic only uses an explicit verb like كان when talking about past or certain other structures:

• كانت المصابيح سليمة = the headlights were fine

Arabic often uses و = and very freely in lists.

So:

• المصابيح الأمامية والمنبه والمساحات

This is perfectly normal Arabic style. Written Arabic may also use commas, but the repeated linking with و is very common.

So the structure is simply:

• item 1 and item 2 and item 3

Yes, that is also grammatically possible.

You could say:

• تقرير الفحص يقول إن ...

That would be a more subject-first order:

• The inspection report says that ...

But the actual sentence uses the very common Arabic verb-first order:

• يقول تقرير الفحص إن ...

Both are possible, but the given version sounds very natural in MSA.

For most everyday reading, they are not written, but they still exist in full formal grammar.

In fully vocalized form, you could analyze the endings roughly like this:

• يقولُ
• تقريرُ الفحصِ
• إنَّ
• المصابيحَ الأماميةَ والمنبّهَ والمسّاحاتِ ... depending on full syntactic analysis and reading tradition
• سليمةٌ

For a learner, the important practical point is:

• normal Arabic text usually leaves these endings unwritten
• native readers understand them from context
• you do not need them to understand the sentence

At an early stage, it is more important to understand the structure than to worry about supplying every case ending perfectly.

Here it is an adjective meaning front or frontal.

It describes المصابيح:

• المصابيح الأمامية = the front lights / headlights

You can tell it is functioning as an adjective because it matches the noun in:

• definiteness: both have ال
• number: both are plural
• gender: both are feminine plural in form

So this is a standard noun + adjective phrase.
