Honda Instrument Cluster / Gauge Illumination Bulb 14V 1.4W 35506-SA5-003

Genuine Honda bulb 35506-SA5-003 rated at 14V / 1.4W, used as an instrument cluster / gauge illumination bulb in many classic and older Honda models. This small but important part is responsible for backlighting the speedometer, tachometer and other dashboard gauges, improving visibility and driving comfort at night.

The bulb is installed in the instrument cluster assembly and, depending on the model and market version, may be used for gauge backlighting or other dashboard illumination points. Part number 35506-SA5-003 supersedes the older Honda number 35505-SD7-951. For best accuracy, fitment should be confirmed by VIN or by comparing the original bulb removed from the cluster.

OEM numbers

• 35506-SA5-003 – genuine Honda part number
• 35505-SD7-951 – superseded older number

When to replace / symptoms of failure

• instrument cluster backlighting no longer works,
• part of the gauges becomes difficult to read at night,
• uneven illumination across the dashboard,
• intermittent flickering of the cluster lighting,
• burned-out bulb found during cluster removal.

In older vehicles, if one dashboard bulb has failed, the remaining bulbs are often already worn as well. When the cluster is removed, it is practical to inspect the full set.

Installation and service tips

• Disconnect the battery before removing the instrument cluster.
• Handle dashboard trims and cluster plastics carefully, as clips and housings in older Hondas can become brittle with age.
• Always compare the original bulb with the new one for voltage, wattage and socket style.
• Do not force the bulb into the holder, and keep the installation area clean.
• If the cluster is already out, replacing several illumination bulbs at the same time can save time and avoid repeated disassembly later.
• Before reinstalling all dashboard trims, test the backlighting to confirm even illumination.
