A Bolero fog lamp pair is standard on the B6(O) and on the top B8, set low in the front bumper below the new grille. The B4 and B6 do not get front fog lamps, though owners can add them later with the right wiring.
On a Bolero they pay off most during dense north Indian winter fog and on dusty, unlit rural stretches. Below is how to replace a broken unit, find the right bulb and add a pair to a lower trim without electrical trouble.

Front fog lamps were listed as a new addition when the latest range arrived, so a lamp on many older Boleros is likely an accessory. Look at the bumper: a factory unit sits inside a moulded recess with a neat bezel, while an add on unit often hangs from a bracket under the bumper.
Bolero fog lamp original part and bulb type
When a stone cracks the lens, the cleanest fix is the genuine lamp assembly from a Mahindra dealer, quoted by part number from your vehicle identification number. To find the bulb type, read the owner's manual lighting table, or reach behind the bumper, twist the holder free and note the code moulded into the bulb's base. Carry the removed bulb with you when buying; matching the base is more important than matching the brightness. Sealed LED units have no separate bulb, so the complete housing gets swapped.
Replacing a broken unit
- Switch off the ignition and lights.
- Swing the wheels to full lock, then fold back the front edge of the arch liner for access.
- Unplug the connector by pressing its tab.
- Undo the mounting screws and pull the lamp out from the front or back, depending on the bezel design.
- Fit the new lamp, plug in, and check that it lights before refitting the liner.
- Aim it on a flat wall so the beam top stays below the headlamp beam.
Adding fog lamps to a B4 or B6
The safest route is the dealer's accessory kit or the same lamps used on the B6(O), with a proper relay, fuse and switch. Cheap kits with thin wire and no relay draw current through the light switch and can melt it. Ask the fitter to take power through a fused relay so the lamps only work with the parking lamps on. If you drive mostly in towns with street lights, the money may be better spent on clean headlamp lenses and correctly aimed headlamps.
When a Bolero driver should switch them on
The beam is spread wide and kept low, close to the tarmac, so it picks out the kerb, the shoulder and lane paint when fog or a downpour hides everything further ahead. In clear weather on a dark highway they add little and dazzle oncoming drivers on a bend. Switch them off once visibility improves. Avoid white bright aftermarket bulbs; a yellow or warm beam cuts through fog better and is kinder to other road users. Two lamp technologies get their own pages: projector fog lamp and LED fog lamp.
Signs the fog lamp needs attention
Trouble shows as mist or beads of water behind the glass after monsoon driving, a beam knocked upward by a front bump, a flicker every time the Bolero hits a rut, or one lamp clearly weaker than its partner. Moisture usually means a cracked lens or perished seal, and the lamp will rust inside if left. A flicker often points to a loose connector rather than a failed bulb. Have a mechanic look over any front end damage behind the lamp, since the bumper bracket also supports other parts.

Questions owners ask
Which Bolero variant has fog lamps?
The B6(O) and the B8 have front fog lamps from the factory. The B4 and B6 do not.
Where can I get a Bolero fog lamp original?
An authorised Mahindra dealer can order the genuine assembly by part number. Give them your vehicle identification number so they pick the right one for your range.
Can I fit fog lamps to a Bolero B6?
Yes, with the dealer accessory kit or the same lamps as the B6(O). Make sure the wiring uses a relay and a fuse.
What bulb does the Bolero fog lamp use?
The handbook lighting table lists it, or read the code on the old bulb. Units built as sealed LEDs are changed complete.
Why is there water inside my Bolero fog lamp?
Most often the lens has a hairline crack or the rubber seal has aged. Replace the unit or reseal it soon, because moisture corrodes the reflector and connector.
