انا مش معايا العربيه بس من البحث لقيت ان العلامة ديه مش كود اعطال ده مجرد كود او فيرجن لتصميم العدادات اللى عندك وفيه موديلات تانية 34 او 35

It's not a light. There isn't a bulb behind the lettering at all. It's always been there and you haven't noticed it. This by far isnt' the first time I've had someone that just noticed this. It's just lettering printed on the instrument cluster face, nothing more. It's a designation for the version of cluster printed on there by the manufacturer. Once it leaves the plant that doesn't mean anything to anyone.
