Physically H11 and H8 bulbs are identical to each other in dimensions and filament placement. But H11 is brighter with a draw of 55W and the H8 is lower in brightness with a draw of only 35W. H11 is used as fog lamp bulbs and in some cars also as low beam headlight bulbs whereas the H8 is used only as foglight bulbs in automobiles. The light output of 12V H11 and 12V H8 bulbs are typically 1350 and 800 lumens respectively.
If you wish to put H11 bulbs in a light housing meant only for H8 bulbs you can but you may have to trim the center locating tab of the H11 a little, because it is wider by a few millimeters compared to the H8's.
In the Swift it is very easy to modify the fog lamp housing to take the brighter H11 bulb. It takes less than 10 minutes to do each lamp with care. It is better to modify the housing once rather than trim the center tab of the H11 bulb whenever you need to replace a bulb.
H8 bulb on the left and H11 bulb on the right. H8 is Halonix which came as OE and H11 is Philips.
H8 bulb in holder, it fits well.
H11 bulb in holder. Center tab doesn't go in and the bulb does not sit flush.
Trim the holder/housing at the location as shown below to make H11 bulbs fit.
Results
There is a considerable improvement in light output as expected to the stock H8 bulbs. Stock H8 bulbs were weak and didn't put out any useful illumination and now with H11 bulbs the lamps do make their presence known and illuminates to the sides and to the front a bit better. For a bit more output choose the expensive variants of H11 like Osram Night breaker Plus and Philips Xtreme Vision.
